ab27182cac mmc: socfpga_dw_mmc: Enable/disable SDMMC clock via API
Update the driver to enable or disable the SDMMC clock via
clock driver model API instead of doing it in the driver itself.

This allows for scalability of the driver for various SoCFPGA

38d49808d4 cache: Check dcache availability before calling cache functions
When the data cache (dcache) is disabled, calling related
status functions can lead to compilation errors due to
undefined references.

Adding a !CONFIG_IS_ENABLED(SYS_DCACHE_OFF) check before
invoking dcache_status() (used in common/memsize.c:get_ram_size())
and mmu_status() (from arch/arm/include/asm/io.h).

Without this check, builds with dcache disabled will fail to compile.

f4db066455 arm: socfpga: mailbox: Remove CONFIG_CADENCE_QSPI guard from QSPI mailbox API declarations
The QSPI mailbox API function declarations (mbox_qspi_close and
mbox_qspi_open) in mailbox_s10.h were guarded by CONFIG_CADENCE_QSPI
preprocessor conditional. This prevented their prototypes from being
visible to code that may use the stub implementations when
CONFIG_CADENCE_QSPI is disabled.

Remove the CONFIG_CADENCE_QSPI preprocessor conditional so these functions
are always declared, regardless of the configuration. This avoids potential
build or linkage errors when stubs are used.

a239b0b0b6 Add symlink from gpl-2.0.txt to a COPYING file
While it is good that the "Licenses/" directory contains the text
for all licenses that are applicable to u-boot code, it is harder
to determine at a glance what the default and/or preferred license
is. While humans can look at the Licenses/README file, this is not
machine parseable, making it tricky for license detection tools to
automatically determine/report on the overall / aggregate u-boot
license.

The project previously had a top level COPYING file containing a
short blurb, followed by the GPL license text. This was removed
back in commit eca3aeb352 when
the "Licenses/" directory was introduced. For the benefit of
automated tools, it is helpful to retain a top level COPYING
file in the repository. Rather than duplicate the license text,
however, a symlink from the Licenses/gpl-2.0.txt file should
suffice.

b6d9aa6aaf bootstage: stash boot records to reserved mem before kernel handoff
U-Boot now stashes its bootstage buffer into a reserved memory region
whenever CONFIG_BOOTSTAGE_STASH is enabled, just before exiting to the
kernel. This allows a post boot parser to read a unified timeline
(SPL→U-Boot→Kernel→MCU/DSP) directly from DDR, enabling standardized
and repeatable boot-time profiling across releases and SoCs.

 Call bootstage_stash_default() in announce_and_cleanup()

40888b1e4c scripts: checkpatch.pl: Extend some checks to "env" files
In order for the U-Boot specific tests we've added (along with the long
line test) to be run on ".env" files as well, we need to update the line
in the process function that starts to limit the file extensions that we
test on.

14b784aaf2 Merge patch series "exports overhaul"
Rasmus Villemoes <ravi@prevas.dk> says:

This all started from me wondering "why does this standalone app end
up being so huge"? Oh, it essentially links in its own standard C
library to get strlen() and snprintf(). Which then led to asking "why
don't we export all those standard C functions when we have them
anyway?".

CI has chewed on these and seem happy - it was CI which told me about
the necessity of [1/9]: https://github.com/u-boot/u-boot/pull/813

07588f4ad9 exports.h: bump XF_VERSION
There have been quite a few changes to _exports.h since the last
update of XF_VERSION, also before the previous patches in this series.

I doubt the mechanism is actually being used in practice, it is simply
too fragile: Not only does the list of exported functions depend on
.config, so with the same XF_VERSION the jump table entries could have
different offsets. But getting to the jump table itself from gd to
even call the ->get_version() is fragile, since offsetof(gd_t, jt)
can, and does, change. For example, as recently as commit
d990210702 ("global_data: Remove jump table in SPL").

One really must build one's standalone app against the proper U-Boot
version and config.h. But for good measure, do bump it now.

d957061582 _exports.h: export standard memory/string handling functions
The current list of exported functions lacks quite a few bog-standard C
library functions that we might as well expose, since U-Boot certainly
has them implemented anyway. There's no reason a standalone
application should have its own strlen() implementation or link in a
copy from some tiny libc.

For a customer's standalone app, this means it goes from 95K to 10K.
More importantly, we can ditch the custom toolchain including a
newlibc used to build the standalone app and just use the same
toolchain as used to build u-boot itself.

2ef6c17f7f _exports.h: reorganize a bit
The current list of exported functions is somewhat of a
mess. Reorganize them so that related functionality is kept together:

- console I/O: move vprintf next to printf and the getc/putc functions

- integer parsing: move the *strto* functions together

- standard string.h stuff: move memset() and strcpy() next to strcmp()

- time: move mdelay() next to udelay() and get_timer()

bdbaaee65c exports.h: make sure declarations are in sync with the actual exports
After finishing a later patch in this series, I discovered I had
neglected to update the list of declarations in exports.h to
match. But then I realized I wasn't the first to do that.

Use the existing mechanism and DRY it out.

a78941bc7f exports.c: drop unused dummy function
The !CONFIG_PHY_AQUANTIA defines were already superfluous since
_exports.h does have a CONFIG_PHY_AQUANTIA, so the entries never
existed. In fact, it couldn't have worked, because the defines would
affect both occurences of the mdio_get_current_dev identifier in the

	EXPORT_FUNC(mdio_get_current_dev, struct mii_dev *,
		    mdio_get_current_dev, void)

so the C code would end up containing four copies of

  gd->jt->dummy = dummy

but struct jt_funcs would not and does not have any 'dummy' member.

Now that nothing in _exports.h refers to dummy(), remove the empty
function.
