I recently submitted the clock driver for MT8188. I naively submitted a
driver that was ported from the kernel driver, and mostly work to boot a
kernel.
Recently David Lechner, added support for the clk dump command for
Mediatek clock drivers, so I used it to check the MT8188 and found
several issues fixed on this series:
- removed topckgen_cg, gates are now part of topckgen
- fixed several parents clocks
- added missing fixed clocks
While at it, I also refactored a bit the driver to improve readability,
and future additions to it.
Link: https://lore.kernel.org/r/20260202-mt8188-fix-clock-v2-0-b39bddfcac66@baylibre.com
Refactor some part of the driver to improve readability and future
additions:
- use CLK_TOP_NR_CLK for added clocks
- rename the id map to make it more clear that the map applies to top
clocks only
- refactor the id map to improve readability
- xtal2_rate is only used for PLL clocks, so only the apmixedsys clock
tree needs it. Remove it elsewhere.

This series finish the last missing puzzle of required SMBIOS types by:
1) Fixing duplicated handles when multiple instances exist in one type;
2) Implementing the rest of required types 9/16/17/19;
3) Adding version control when printing properties for all types.
Type 9/16/17/19 are generally DT-based, the idea is to write these tables
using a hybrid approach:
Explicit DT definitions under existing '/smbios/smbios' take precedence,
with fallback to scan and interpret values from the entire DT.
Moreover, all below APIs:
smbios_get_val_si()
smbios_get_u64_si()
smbios_add_prop_si()
are on top of sysinfo, thus allow vendors to get values from other
subsystems by implementing their own sysinfo driver if needed.

This commit implements SMBIOS Type 19 (Memory Array Mapped Address)
generation with a hybrid approach supporting both:
1. Explicit definition via Device Tree 'smbios' node:
Child node under '/smbios/smbios/memory-array-mapped-address' will be
used to populate as individual Type 19 structure directly.
- Properties follow SMBIOS field names with lowercase letters and
hyphen-separated words (e.g., 'starting-address', 'ending-address',
'partition-width', etc.).
- This method supports precise platform-defined overrides and system
descriptions.
2. Fallback to automatic DT-based discovery:
If child node under '/smbios/smbios/memory-array-mapped-address' does
not exist, the implementation will:
- Scan all top-level 'memory@' nodes to populate Type 19 structure with
inferred size and location data.
- Scan nodes named or marked as 'memory-controller' and parse
associated 'dimm@' subnodes (if present) to extract DIMM sizes and
map them accordingly.
This dual-mode support enables flexible firmware SMBIOS reporting while
aligning with spec-compliant naming and runtime-detected memory topology.
Type 19 support is under GENERATE_SMBIOS_TABLE_VERBOSE to avoid
increasing rom size for those platforms which only require basic SMBIOS
support.

This commit introduces support for generating SMBIOS Type 9 (System Slot)
tables using a hybrid approach:
1. Explicit Device Tree definitions:
Child node under '/smbios/smbios/system-slot' will be interpreted as
individual slot definitions.
- Each child represents a slot (e.g., isa, pcmcia, etc.).
- Properties follow the SMBIOS specification using lowercase
hyphen-separated names such as 'slot-type', 'slot-id',
'segment-group-number', 'bus-number', 'slot-information', etc.
- This approach allows full customization of each system slot and is
especially suitable for platforms with well-defined slot topology.
2. Automatic detection fallback:
If child node under '/smbios/smbios/system-slot' does not exist, the
implementation will scan the entire device tree for nodes whose
'device_type' matches known slot-related types ("pci", "isa", "pcmcia",
etc.).
- When a match is found, default values or heuristics are applied to
populate to the System Slot table.
- This mode is useful for platforms that lack explicit SMBIOS nodes
but still expose slot topology via standard DT conventions.
Together, two approaches ensure that SMBIOS Type 9 entries are available
whether explicitly described or automatically derived.

Some smbios types can have multiple instances (e.g. Type 7, 9, 16, 17,
19), thus the 'handle' argument should be a pointer so that the value
can be accumulated when writing all the instances.

This patch set primarily removes unused DECLARE_GLOBAL_DATA_PTR

Many files declare DECLARE_GLOBAL_DATA_PTR and include
asm/global_data.h even though gd is never used. In these cases,
asm/global_data.h is effectively treated as a proxy header, which is
not a good practice.
Following the Include What You Use principle, files should include
only the headers they actually depend on, rather than relying on
global_data.h indirectly. This approach is also adopted in Linux kernel

The first few patches are prepartion to avoid building break after
remove the including of global_data.h.

This commit updates the RAM region filtering logic in
board_get_usable_ram_top() to skip any memory regions whose start address
is above 4GB. Previously, only the end address was capped at 4GB, but
regions entirely above this threshold were still considered.
Typically, the following memory map entries would cause
board_get_usable_ram_top() to return 0x100000000, which is incorrect.
start=00000000, end=00001000, type=16

Since commit 27cc5951c8 ("include: env: ti: add default for
do_main_cpsw0_qsgmii_phyinit"), the value of the environment variable
do_main_cpsw0_qsgmii_phyinit happened to remain '0' and couldn't be
changed without user intervention. This behavior is due to the following
cyclic dependency:
A) ti_common.env sets do_main_cpsw0_qsgmii_phyinit to '0' and its value
can only be updated automatically by main_cpsw0_qsgmii_phyinit.
B) main_cpsw0_qsgmii_phyinit is defined in j721e.env and it can run only
if 'do_main_cpsw0_qsgmii_phyinit' is already '1' which isn't possible
unless the user manually assigns the value.
Fix the aforementioned cyclic dependency by using board_late_init() to
detect the QSGMII Daughtercard and set do_main_cpsw0_qsgmii_phyinit.
Additionally, to address the issue of do_main_cpsw0_qsgmii_phyinit being
'undefined' for other platforms, replace:
if test ${do_main_cpsw0_qsgmii_phyinit} -eq 1;
with:
if env exists do_main_cpsw0_qsgmii_phyinit;
in ti_common.env.

libfdt expects FDT/DTO blobs to be 8-byte aligned. When loading the
base FDT or overlays from a FIT, the mapped buffer may be unaligned,
which can break fdt_open_into() on strict-alignment architectures.
boot_get_fdt_fit() relocates the base FDT with boot_relocate_fdt()
before applying overlays. That uses the bootm memory map and can
overlap with the FIT buffer when the FIT is loaded into RAM,
corrupting data needed to load the kernel and ramdisk.
Allocate writable, 8-byte aligned copies of the base FDT and overlays
with memalign() and fdt_open_into(). Grow the base buffer as needed,
apply overlays to it and pack the final tree. Free each temporary
overlay copy after application and check fdt_pack() errors.
