86b1aad541 spl: mmc: Fix check of CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR
When Falcon Mode is enabled, SPL needs to check the value of
CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR. Unfortunately, it was using the
CONFIG_VAL(SYS_MMCSD_RAW_MODE_ARGS_SECTOR) which converts it into
CONFIG_SPL_SYS_MMCSD_RAW_MODE_ARGS_SECTOR when CONFIG_SPL_BUILD is
enabled. CONFIG_SPL_SYS_MMCSD_RAW_MODE_ARGS_SECTOR does not exist in
common/spl/Kconfig. Replaced with
defined(CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR).

fe85863086 armv8: Skip PIE in SPL due to load alignment fault.
When PIE is enabled in start.S, u-boot/-spl use __rel_dyn_start
and _rel_dyn_end symbol to be loaded to and executed at a
different address than it was linked at.

u-boot-spl.lds is used in SPL build, but relocation information
section(.rela*) were discarded.
In line number 80 in arch/arm/cpu/armv8/u-boot-spl.lds
 /DISCARD/ : { *(.rela*) }

If PIE enabled in SPL, __rel_dyn_start which is defined as
.rel_dyn_start in sections.c will be apended to the end of
.bss section.

In our ASPEED case, size of .bss section would let .rel_dyn_start
without 8-byte alignment, leading to alignment fault when
executing ldp instuction in pie_fix_loop.

726a802fda arm: Use builtins for ffs/fls
Since ARMv5, the clz instruction allows for efficient implementation of
ffs/fls with builtins. Until ARMv7 (with Thumb-2), this instruction is
only available in ARM mode. LTO makes it difficult to force specific
functions to be in ARM mode, as it is effectively a form of very
aggressive inlining. To work around this, fls/ffs are implemented in
assembly for ARMv5 and ARMv6 when compiling U-Boot in Thumb mode.
Overall, this saves around 75 bytes per call.

This code is synced with v5.15 of the Linux kernel.

5d3758178b Merge branch '2023-08-15-add-SGMII-support-for-TI-j7200' into next
To quote the author:
This series adds support for SGMII mode to the CPSW driver to enable the
functionality on TI's J7200 SoC.

Supporting SGMII mode also requires changes to the WIZ driver which acts
as a wrapper for the SerDes used by the CPSW MAC to transmit data to the
Ethernet PHY daughtercard mounted on the I2C GPIO Expander 2 connector
on the J7200 EVM.

Powering on and resetting the Ethernet PHY requires MDIO support which
is added to the CPSW driver.

For supporting DMA transactions from the MAIN CPSW instance to the A72
Host on J7200 SoC, the corresponding PSI-L endpoint information is added
for the J721E SoC, which is applicable to J7200 SoC as well.

The SGMII daughtercard used for testing SGMII mode has TI's DP83869 PHY.
Thus, enable the config for DP83869 driver functionality. Also, enable
GPIO HOG config.

aaf5b59230 gpio: Use separate bitfield array to indicate GPIO is claimed
The current gpio-uclass design uses name field in struct gpio_dev_priv as
an indicator that GPIO is claimed by consumer. This overloads the function
of name field and does not work well for named pins not configured as GPIO
pins.

Introduce separate bitfield array as the claim indicator.

This unbreaks dual-purpose AF and GPIO operation on STM32MP since commit
2c38f7c318 ("pinctrl: pinctrl_stm32: Populate uc_priv->name[] with pinmux node's name")
where any pin which has already been configured as AF could no longer be
claimed as dual-purpose GPIO. This is important for pins like STM32 MMCI
st,cmd-gpios .

To quote the author:

The commit 4fcba5d556 ("regulator: implement basic reference counter")
have made it more important to keep fixed/gpio regulators enable/disable
state in balance.

This series fixes an inbalance in the mmc_dw driver and changes to use
the more relaxed regulator_set_enable_if_allowed function for a few
other drivers.

The regulator_set_enable_if_allowed function is more relaxed and will
return ENOSYS if the provided regulator is NULL or when DM_REGULATOR
was disabled. Using the following call convention should be safe:

  ret = regulator_set_enable_if_allowed(<supply>, <true|false>);
  if (ret && ret != -ENOSYS)

1d4bbdf3e4 bootstd: cros: Add private info for ChromiumOS
Create a new private structure to hold information gleaned from the disk.
This will allow separation between reading of the bootflow information and
(later) reading the whole kernel.

1a0810924a bootstd: Move common zimage functions to bootm.h
We want to avoid using #ifdefs around header files and in the code. It
makes sense to collect the various functions used for loading images into
a single header which can be included by all architectures. The best place
for this is the arch-neutral bootm.h header, so use that.

Move some zimage functions into this bootm.h header.

c5dca50bbb bootstd: cros: Simplify setup and cmdline expressions
Create a common base from which the other parts are offset and make all
of the offsets related to that. This makes the code a little easier to
read.

Use X86_ prefixes for the two values which are x86-specific.

Drop OFFSET_BASE since it is available in a header field.

Drop the unnecessary 'start' variable too.
