-* ARM L2 Cache Controller
-
-ARM cores often have a separate L2C210/L2C220/L2C310 (also known as PL210/PL220/
-PL310 and variants) based level 2 cache controller. All these various implementations
-of the L2 cache controller have compatible programming models (Note 1).
-Some of the properties that are just prefixed "cache-*" are taken from section
-3.7.3 of the Devicetree Specification which can be found at:
-https://www.devicetree.org/specifications/
-
-The ARM L2 cache representation in the device tree should be done as follows:
-
-Required properties:
-
-- compatible : should be one of:
-  "arm,pl310-cache"
-  "arm,l220-cache"
-  "arm,l210-cache"
-  "bcm,bcm11351-a2-pl310-cache": DEPRECATED by "brcm,bcm11351-a2-pl310-cache"
-  "brcm,bcm11351-a2-pl310-cache": For Broadcom bcm11351 chipset where an
-     offset needs to be added to the address before passing down to the L2
-     cache controller
-  "marvell,aurora-system-cache": Marvell Controller designed to be
-     compatible with the ARM one, with system cache mode (meaning
-     maintenance operations on L1 are broadcasted to the L2 and L2
-     performs the same operation).
-  "marvell,aurora-outer-cache": Marvell Controller designed to be
-     compatible with the ARM one with outer cache mode.
-  "marvell,tauros3-cache": Marvell Tauros3 cache controller, compatible
-     with arm,pl310-cache controller.
-- cache-unified : Specifies the cache is a unified cache.
-- cache-level : Should be set to 2 for a level 2 cache.
-- reg : Physical base address and size of cache controller's memory mapped
-  registers.
-
-Optional properties:
-
-- arm,data-latency : Cycles of latency for Data RAM accesses. Specifies 3 cells of
-  read, write and setup latencies. Minimum valid values are 1. Controllers
-  without setup latency control should use a value of 0.
-- arm,tag-latency : Cycles of latency for Tag RAM accesses. Specifies 3 cells of
-  read, write and setup latencies. Controllers without setup latency control
-  should use 0. Controllers without separate read and write Tag RAM latency
-  values should only use the first cell.
-- arm,dirty-latency : Cycles of latency for Dirty RAMs. This is a single cell.
-- arm,filter-ranges : <start length> Starting address and length of window to
-  filter. Addresses in the filter window are directed to the M1 port. Other
-  addresses will go to the M0 port.
-- arm,io-coherent : indicates that the system is operating in an hardware
-  I/O coherent mode. Valid only when the arm,pl310-cache compatible
-  string is used.
-- interrupts : 1 combined interrupt.
-- cache-size : specifies the size in bytes of the cache
-- cache-sets : specifies the number of associativity sets of the cache
-- cache-block-size : specifies the size in bytes of a cache block
-- cache-line-size : specifies the size in bytes of a line in the cache,
-  if this is not specified, the line size is assumed to be equal to the
-  cache block size
-- cache-id-part: cache id part number to be used if it is not present
-  on hardware
-- wt-override: If present then L2 is forced to Write through mode
-- arm,double-linefill : Override double linefill enable setting. Enable if
-  non-zero, disable if zero.
-- arm,double-linefill-incr : Override double linefill on INCR read. Enable
-  if non-zero, disable if zero.
-- arm,double-linefill-wrap : Override double linefill on WRAP read. Enable
-  if non-zero, disable if zero.
-- arm,prefetch-drop : Override prefetch drop enable setting. Enable if non-zero,
-  disable if zero.
-- arm,prefetch-offset : Override prefetch offset value. Valid values are
-  0-7, 15, 23, and 31.
-- arm,shared-override : The default behavior of the L220 or PL310 cache
-  controllers with respect to the shareable attribute is to transform "normal
-  memory non-cacheable transactions" into "cacheable no allocate" (for reads)
-  or "write through no write allocate" (for writes).
-  On systems where this may cause DMA buffer corruption, this property must be
-  specified to indicate that such transforms are precluded.
-- arm,parity-enable : enable parity checking on the L2 cache (L220 or PL310).
-- arm,parity-disable : disable parity checking on the L2 cache (L220 or PL310).
-- arm,outer-sync-disable : disable the outer sync operation on the L2 cache.
-  Some core tiles, especially ARM PB11MPCore have a faulty L220 cache that
-  will randomly hang unless outer sync operations are disabled.
-- prefetch-data : Data prefetch. Value: <0> (forcibly disable), <1>
-  (forcibly enable), property absent (retain settings set by firmware)
-- prefetch-instr : Instruction prefetch. Value: <0> (forcibly disable),
-  <1> (forcibly enable), property absent (retain settings set by
-  firmware)
-- arm,dynamic-clock-gating : L2 dynamic clock gating. Value: <0> (forcibly
-  disable), <1> (forcibly enable), property absent (OS specific behavior,
-  preferably retain firmware settings)
-- arm,standby-mode: L2 standby mode enable. Value <0> (forcibly disable),
-  <1> (forcibly enable), property absent (OS specific behavior,
-  preferably retain firmware settings)
-- arm,early-bresp-disable : Disable the CA9 optimization Early BRESP (PL310)
-- arm,full-line-zero-disable : Disable the CA9 optimization Full line of zero
-  write (PL310)
-
-Example:
-
-L2: cache-controller {
-        compatible = "arm,pl310-cache";
-        reg = <0xfff12000 0x1000>;

-        cache-unified;
-        cache-level = <2>;
-	interrupts = <45>;
-};
-
-Note 1: The description in this document doesn't apply to integrated L2
-	cache controllers as found in e.g. Cortex-A15/A7/A57/A53. These
-	integrated L2 controllers are assumed to be all preconfigured by
-	early secure boot code. Thus no need to deal with their configuration
-	in the kernel at all.

-*** Reserved memory regions ***
-
-Reserved memory is specified as a node under the /reserved-memory node.
-The operating system shall exclude reserved memory from normal usage
-one can create child nodes describing particular reserved (excluded from
-normal use) memory regions. Such memory regions are usually designed for
-the special usage by various device drivers.
-
-Parameters for each memory region can be encoded into the device tree
-with the following nodes:
-
-/reserved-memory node
----------------------
-#address-cells, #size-cells (required) - standard definition
-    - Should use the same values as the root node
-ranges (required) - standard definition
-    - Should be empty
-
-/reserved-memory/ child nodes
------------------------------
-Each child of the reserved-memory node specifies one or more regions of
-reserved memory. Each child node may either use a 'reg' property to
-specify a specific range of reserved memory, or a 'size' property with
-optional constraints to request a dynamically allocated block of memory.
-
-Following the generic-names recommended practice, node names should
-reflect the purpose of the node (ie. "framebuffer" or "dma-pool"). Unit
-address (@<address>) should be appended to the name if the node is a
-static allocation.
-
-Properties:
-Requires either a) or b) below.
-a) static allocation
-   reg (required) - standard definition
-b) dynamic allocation
-   size (required) - length based on parent's #size-cells
-                   - Size in bytes of memory to reserve.
-   alignment (optional) - length based on parent's #size-cells
-                        - Address boundary for alignment of allocation.
-   alloc-ranges (optional) - prop-encoded-array (address, length pairs).
-                           - Specifies regions of memory that are
-                             acceptable to allocate from.
-
-If both reg and size are present, then the reg property takes precedence
-and size is ignored.
-
-Additional properties:
-compatible (optional) - standard definition
-    - may contain the following strings:
-        - shared-dma-pool: This indicates a region of memory meant to be
-          used as a shared pool of DMA buffers for a set of devices. It can
-          be used by an operating system to instantiate the necessary pool
-          management subsystem if necessary.
-        - vendor specific string in the form <vendor>,[<device>-]<usage>
-no-map (optional) - empty property
-    - Indicates the operating system must not create a virtual mapping
-      of the region as part of its standard mapping of system memory,
-      nor permit speculative access to it under any circumstances other
-      than under the control of the device driver using the region.
-reusable (optional) - empty property
-    - The operating system can use the memory in this region with the
-      limitation that the device driver(s) owning the region need to be
-      able to reclaim it back. Typically that means that the operating
-      system can use that region to store volatile or cached data that
-      can be otherwise regenerated or migrated elsewhere.
-
-Linux implementation note:
-- If a "linux,cma-default" property is present, then Linux will use the
-  region for the default pool of the contiguous memory allocator.
-
-- If a "linux,dma-default" property is present, then Linux will use the
-  region for the default pool of the consistent DMA allocator.
-
-Device node references to reserved memory
------------------------------------------
-Regions in the /reserved-memory node may be referenced by other device
-nodes by adding a memory-region property to the device node.
-
-memory-region (optional) - phandle, specifier pairs to children of /reserved-memory
-
-Example
--------
-This example defines 3 contiguous regions are defined for Linux kernel:
-one default of all device drivers (named linux,cma@72000000 and 64MiB in size),
-one dedicated to the framebuffer device (named framebuffer@78000000, 8MiB), and
-one for multimedia processing (named multimedia-memory@77000000, 64MiB).

-Linker-Generated Arrays
-=======================
-
-A linker list is constructed by grouping together linker input
-sections, each containing one entry of the list. Each input section
-contains a constant initialized variable which holds the entry's
-content. Linker list input sections are constructed from the list
-and entry names, plus a prefix which allows grouping all lists
-together. Assuming _list and _entry are the list and entry names,
-then the corresponding input section name is
-
-::
-
-  .u_boot_list_ + 2_ + @_list + _2_ + @_entry
-
-and the C variable name is
-
-::
-
-  _u_boot_list + _2_ + @_list + _2_ + @_entry
-
-This ensures uniqueness for both input section and C variable name.
-
-Note that the names differ only in the first character, "." for the
-section and "_" for the variable, so that the linker cannot confuse
-section and symbol names. From now on, both names will be referred
-to as
-
-::
-
-  %u_boot_list_ + 2_ + @_list + _2_ + @_entry
-
-Entry variables need never be referred to directly.
-
-The naming scheme for input sections allows grouping all linker lists
-into a single linker output section and grouping all entries for a
-single list.
-
-Note the two '_2_' constant components in the names: their presence
-allows putting a start and end symbols around a list, by mapping
-these symbols to sections names with components "1" (before) and
-"3" (after) instead of "2" (within).
-Start and end symbols for a list can generally be defined as
-
-::
-
-  %u_boot_list_2_ + @_list + _1_...
-  %u_boot_list_2_ + @_list + _3_...
-
-Start and end symbols for the whole of the linker lists area can be
-defined as
-
-::
-
-  %u_boot_list_1_...
-  %u_boot_list_3_...
-
-Here is an example of the sorted sections which result from a list
-"array" made up of three entries : "first", "second" and "third",
-iterated at least once.
-
-::
-
-  .u_boot_list_2_array_1
-  .u_boot_list_2_array_2_first
-  .u_boot_list_2_array_2_second
-  .u_boot_list_2_array_2_third
-  .u_boot_list_2_array_3
-
-If lists must be divided into sublists (e.g. for iterating only on
-part of a list), one can simply give the list a name of the form
-'outer_2_inner', where 'outer' is the global list name and 'inner'
-is the sub-list name. Iterators for the whole list should use the
-global list name ("outer"); iterators for only a sub-list should use
-the full sub-list name ("outer_2_inner").
-
-Here is an example of the sections generated from a global list
-named "drivers", two sub-lists named "i2c" and "pci", and iterators
-defined for the whole list and each sub-list:
-
-::
-
-  %u_boot_list_2_drivers_1
-  %u_boot_list_2_drivers_2_i2c_1
-  %u_boot_list_2_drivers_2_i2c_2_first
-  %u_boot_list_2_drivers_2_i2c_2_first
-  %u_boot_list_2_drivers_2_i2c_2_second
-  %u_boot_list_2_drivers_2_i2c_2_third
-  %u_boot_list_2_drivers_2_i2c_3
-  %u_boot_list_2_drivers_2_pci_1
-  %u_boot_list_2_drivers_2_pci_2_first
-  %u_boot_list_2_drivers_2_pci_2_second

-
-    List of customizations:
-
-    * Moved the *duplicate C object description* warnings for function
-      declarations in the nitpicky mode. See Sphinx documentation for
-      the config values for ``nitpick`` and ``nitpick_ignore``.
-
-    * Add option 'name' to the "c:function:" directive.  With option 'name' the
-      ref-name of a function can be modified. E.g.::
-
-          .. c:function:: int ioctl( int fd, int request )
-             :name: VIDIOC_LOG_STATUS
-
-      The func-name (e.g. ioctl) remains in the output but the ref-name changed
-      from 'ioctl' to 'VIDIOC_LOG_STATUS'. The function is referenced by::
-
-          * :c:func:`VIDIOC_LOG_STATUS` or
-          * :any:`VIDIOC_LOG_STATUS` (``:any:`` needs sphinx 1.3)
-
-     * Handle signatures of function-like macros well. Don't try to deduce
-       arguments types of function-like macros.

-
-    The ``kernel-include`` reST-directive is a replacement for the ``include``
-    directive. The ``kernel-include`` directive expand environment variables in
-    the path name and allows to include files from arbitrary locations.
-
-    .. hint::
-
-      Including files from arbitrary locations (e.g. from ``/etc``) is a
-      security risk for builders. This is why the ``include`` directive from
-      docutils *prohibit* pathnames pointing to locations *above* the filesystem
-      tree where the reST document with the include directive is placed.
-
-    Substrings of the form $name or ${name} are replaced by the value of
-    environment variable name. Malformed variable names and references to
-    non-existing variables are left unchanged.

-    scalable figure and image handling
-    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-    Sphinx extension which implements scalable image handling.
-
-    :copyright:  Copyright (C) 2016  Markus Heiser
-    :license:    GPL Version 2, June 1991 see Linux/COPYING for details.
-
-    The build for image formats depend on image's source format and output's
-    destination format. This extension implement methods to simplify image
-    handling from the author's POV. Directives like ``kernel-figure`` implement
-    methods *to* always get the best output-format even if some tools are not
-    installed. For more details take a look at ``convert_image(...)`` which is
-    the core of all conversions.
-
-    * ``.. kernel-image``: for image handling / a ``.. image::`` replacement
-
-    * ``.. kernel-figure``: for figure handling / a ``.. figure::`` replacement
-
-    * ``.. kernel-render``: for render markup / a concept to embed *render*
-      markups (or languages). Supported markups (see ``RENDER_MARKUP_EXT``)
-
-      - ``DOT``: render embedded Graphviz's **DOC**
-      - ``SVG``: render embedded Scalable Vector Graphics (**SVG**)
-      - ... *developable*
-
-    Used tools:
-
-    * ``dot(1)``: Graphviz (http://www.graphviz.org). If Graphviz is not
-      available, the DOT language is inserted as literal-block.
-
-    * SVG to PDF: To generate PDF, you need at least one of this tools:
-
-      - ``convert(1)``: ImageMagick (https://www.imagemagick.org)
-
-    List of customizations:
-
-    * generate PDF from SVG / used by PDF (LaTeX) builder
-
-    * generate SVG (html-builder) and PDF (latex-builder) from DOT files.
-      DOT: see http://www.graphviz.org/content/dot-language

-=head1 DESCRIPTION
-
-Convert a C header or source file (C_FILE), into a ReStructured Text
-included via ..parsed-literal block with cross-references for the
-documentation files that describe the API. It accepts an optional
-EXCEPTIONS_FILE with describes what elements will be either ignored or
-be pointed to a non-default reference.
-
-The output is written at the (OUT_FILE).
-
-It is capable of identifying defines, functions, structs, typedefs,
-enums and enum symbols and create cross-references for all of them.
-It is also capable of distinguish #define used for specifying a Linux
-ioctl.
-
-The EXCEPTIONS_FILE contain two rules to allow ignoring a symbol or
-to replace the default references by a custom one.
-
-Please read Documentation/doc-guide/parse-headers.rst at the Kernel's
-tree for more details.

-    flat-table
-    ~~~~~~~~~~
-
-    Implementation of the ``flat-table`` reST-directive.
-
-    :copyright:  Copyright (C) 2016  Markus Heiser
-    :license:    GPL Version 2, June 1991 see linux/COPYING for details.
-
-    The ``flat-table`` (:py:class:`FlatTable`) is a double-stage list similar to
-    the ``list-table`` with some additional features:
-
-    * *column-span*: with the role ``cspan`` a cell can be extended through
-      additional columns
-
-    * *row-span*: with the role ``rspan`` a cell can be extended through
-      additional rows
-
-    * *auto span* rightmost cell of a table row over the missing cells on the
-      right side of that table-row.  With Option ``:fill-cells:`` this behavior
-      can changed from *auto span* to *auto fill*, which automaticly inserts
-      (empty) cells instead of spanning the last cell.
-
-    Options:
-
-    * header-rows:   [int] count of header rows
-    * stub-columns:  [int] count of stub columns
-    * widths:        [[int] [int] ... ] widths of columns
-    * fill-cells:    instead of autospann missing cells, insert missing cells
-
-    roles:
-
-    * cspan: [int] additionale columns (*morecols*)
-    * rspan: [int] additionale rows (*morerows*)

-License identifier syntax
--------------------------
-
-1. Placement:
-
-   The SPDX license identifier in U-Boot files shall be added at the first
-   possible line in a file which can contain a comment.  For the majority
-   or files this is the first line, except for scripts which require the
-   '#!PATH_TO_INTERPRETER' in the first line.  For those scripts the SPDX
-   identifier goes into the second line.
-
-|
-
-2. Style:
-
-   The SPDX license identifier is added in form of a comment.  The comment
-   style depends on the file type::
-
-      C source:	// SPDX-License-Identifier: <SPDX License Expression>
-      C header:	/* SPDX-License-Identifier: <SPDX License Expression> */
-      ASM:	/* SPDX-License-Identifier: <SPDX License Expression> */
-      scripts:	# SPDX-License-Identifier: <SPDX License Expression>
-      .rst:	.. SPDX-License-Identifier: <SPDX License Expression>
-      .dts{i}:	// SPDX-License-Identifier: <SPDX License Expression>
-
-   If a specific tool cannot handle the standard comment style, then the
-   appropriate comment mechanism which the tool accepts shall be used. This
-   is the reason for having the "/\* \*/" style comment in C header
-   files. There was build breakage observed with generated .lds files where
-   'ld' failed to parse the C++ comment. This has been fixed by now, but
-   there are still older assembler tools which cannot handle C++ style
-   comments.
-
-|
-
-3. Syntax:
-
-   A <SPDX License Expression> is either an SPDX short form license
-   identifier found on the SPDX License List, or the combination of two
-   SPDX short form license identifiers separated by "WITH" when a license
-   exception applies. When multiple licenses apply, an expression consists
-   of keywords "AND", "OR" separating sub-expressions and surrounded by
-   "(", ")" .
-
-   License identifiers for licenses like [L]GPL with the 'or later' option
-   are constructed by using a "+" for indicating the 'or later' option.::
-
-      // SPDX-License-Identifier: GPL-2.0+
-      // SPDX-License-Identifier: LGPL-2.1+
-
-   WITH should be used when there is a modifier to a license needed.
-   For example, the linux kernel UAPI files use the expression::
-
-      // SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
-      // SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
-
-   Other examples using WITH exceptions found in the linux kernel are::
-
-      // SPDX-License-Identifier: GPL-2.0 WITH mif-exception
-      // SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
-
-   Exceptions can only be used with particular License identifiers. The
-   valid License identifiers are listed in the tags of the exception text
-   file.
-
-   OR should be used if the file is dual licensed and only one license is
-   to be selected.  For example, some dtsi files are available under dual
-   licenses::
-
-      // SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
-
-   Examples from U-Boot for license expressions in dual licensed files::
-
-      // SPDX-License-Identifier: GPL-2.0 OR MIT
-      // SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
-
-   AND should be used if the file has multiple licenses whose terms all
-   apply to use the file. For example, if code is inherited from another
-   project and permission has been given to put it in U-Boot, but the
-   original license terms need to remain in effect::
-
-      // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
-
-   Another other example where both sets of license terms need to be
-   adhered to is::
-
-      // SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+

- * [ NOTE 1 ]:
- * Data cache (L1 D$ or SL$) entire invalidate operation or data cache disable
- * operation may result in unexpected behavior and data loss even if we flush
- * data cache right before invalidation. That may happens if we store any context
- * on stack (like we store BLINK register on stack before function call).
- * BLINK register is the register where return address is automatically saved
- * when we do function call with instructions like 'bl'.
- *
- * There is the real example:
- * We may hang in the next code as we store any BLINK register on stack in
- * invalidate_dcache_all() function.
- *
- * void flush_dcache_all() {
- *     __dc_entire_op(OP_FLUSH);
- *     // Other code //
- * }
- *
- * void invalidate_dcache_all() {
- *     __dc_entire_op(OP_INV);
- *     // Other code //
- * }
- *
- * void foo(void) {
- *     flush_dcache_all();
- *     invalidate_dcache_all();
- * }
- *
- * Now let's see what really happens during that code execution:
- *
- * foo()
- *   |->> call flush_dcache_all
- *     [return address is saved to BLINK register]
- *     [push BLINK] (save to stack)              ![point 1]
- *     |->> call __dc_entire_op(OP_FLUSH)
- *         [return address is saved to BLINK register]
- *         [flush L1 D$]
- *         return [jump to BLINK]
- *     <<------
- *     [other flush_dcache_all code]
- *     [pop BLINK] (get from stack)
- *     return [jump to BLINK]
- *   <<------
- *   |->> call invalidate_dcache_all
- *     [return address is saved to BLINK register]
- *     [push BLINK] (save to stack)               ![point 2]
- *     |->> call __dc_entire_op(OP_FLUSH)
- *         [return address is saved to BLINK register]
- *         [invalidate L1 D$]                 ![point 3]
- *         // Oops!!!
- *         // We lose return address from invalidate_dcache_all function:
- *         // we save it to stack and invalidate L1 D$ after that!
- *         return [jump to BLINK]
- *     <<------
- *     [other invalidate_dcache_all code]
- *     [pop BLINK] (get from stack)
- *     // we don't have this data in L1 dcache as we invalidated it in [point 3]
- *     // so we get it from next memory level (for example DDR memory)
- *     // but in the memory we have value which we save in [point 1], which
- *     // is return address from flush_dcache_all function (instead of
- *     // address from current invalidate_dcache_all function which we
- *     // saved in [point 2] !)
- *     return [jump to BLINK]
- *   <<------
- *   // As BLINK points to invalidate_dcache_all, we call it again and
- *   // loop forever.
- *
- * Fortunately we may fix that by using flush & invalidation of D$ with a single
- * one instruction (instead of flush and invalidation instructions pair) and
- * enabling force function inline with '__attribute__((always_inline))' gcc
- * attribute to avoid any function call (and BLINK store) between cache flush
- * and disable.
- *
- *
- * [ NOTE 2 ]:
- * As of today we only support the following cache configurations on ARC.
- * Other configurations may exist in HW (for example, since version 3.0 HS
- * supports SL$ (L2 system level cache) disable) but we don't support it in SW.
