A few fixes/missing changes for UFS:
- remove unused ufs_post_bind() declaration
- Disable UTP command timeout in slow mode
- Missing MediaTek UFS PHY Driver to be used with the UFS driver
Remove the "phandle = <0x..>;" properties from the DT diff between
unpatched base DT and U-Boot augmented DT if DEVICE_TREE_DEBUG=1.
The phandle numbers are only generated by DTC, but not referenced
anywhere in the DT, because the original references are specifically
not replaced by phandle numbers when recent DTC is invoked with the
-I dts -O dts flags . The phandle number are therefore only a noise
in the diff, filter them out.

The exported sub_make_done variable leaks into the environment of all
child processes. When make targets like tcheck spawn independent make
invocations with O=, those child makes inherit sub_make_done=1, skip
the KBUILD_OUTPUT setup and try to build in the source tree.
There is a workaround that resets sub_make_done to 0 for specific test
targets, but this isn't great since it has tolist every target that
spawns independent make invocations.
Instead, unexport sub_make_done once we are in the final make
invocation. The direct sub-make already has the value in its
environment from the export, and no further propagation is needed.
This also allows the per-target workaround to be removed.

The get_ram_size() function fails to restore the original RAM data when
the data cache is enabled. This issue was observed on an AM625 R5 SPL
with 512MB of RAM and is a regression that became visible with
commit bc07851897 ("board: ti: Pull redundant DDR functions to a common
location and Fixup DDR size when ECC is enabled").
Observed boot failure messages:
Warning: Did not detect image signing certificate. Skipping authentication to prevent boot failure. This will fail on Security Enforcing(HS-SE) devices
Authentication passed

The system then hangs. This indicates that without a data cache flush,
data in the cache is not coherent with RAM, preventing the system from
booting. This was verified by printing the content of this address when
the issue occurs.
Add a data cache flush after each restore operation to resolve this
issue.

With ENV_WRITEABLE_LIST only specific environment variables lisetd in
CFG_ENV_FLAGS_LIST_STATIC are read from the u-boot environment storage.
All other environment variables are set to default values and are not
written back to the storage.
The u-boot environment usually stays for the lifetime of the product.
There is no A/B copy mechanism as for the firmware itself. That means
that incompatible changes to environment variables in future u-boot
versions may lead to serious issues if the old environment is used with
a new u-boot version or vice versa.
Having this protection in place ensures that only a limited set of
environment variables are persisted across u-boot versions. All the
macros not listed in CFG_ENV_FLAGS_LIST_STATIC are now part of the
u-boot binary which is redundant and immutable. This guarantees that
the u-boot version and the default values of these environment variables
are always in sync and cannot be changed at runtime.
ustate and rastate are not relevant for u-boot itself. ustate is used
by swupdate which persists the transaction state in the environment.
rastate is a similar variable used by another user space application.

Rework the boot state machine to a significantly simpler and more
robust implementation. The basic idea is to revert to the previous
partition whenever an issue is detected during the boot process.
- Broken SPL
If one of the two SPLs does not boot, the ROM code of the i.MX8 SoC
automatically starts the second SPL from the second boot partition.
For example, if the system's active partition is A but the SPL from
partition A is broken, the ROM code automatically uses the SPL/u-boot
from partition B.
Proceeding with this boot procedure would lead to booting the kernel/
rootfs from partition A, which could potentially successfully boot
the system and allow the user to apply the firmware update with the
broken SPL again. This would lead to a non-bootable system because
the second update would overwrite the last working bootloader.
To prevent such situations, zigzag boots are detected and the system
reverts to the previous partition rather than booting the kernel/rootfs
from the currently active partition. Detecting zigzag boots is done
via the new fallback variable.
To make this state machine even more consistent, the partitionset_active
variable is no longer used to determine the active partition during
boot. Instead, the active partition is always read from the eMMC
partconf registers.
For backward compatibility, the partitionset_active variable is still
updated whenever a partition switch occurs. However, u-boot no longer
relies on this variable, as it could potentially be out of sync with
the actual partition state, leading to situations where the ROM code
of the i.MX8 SoC would be out of sync with u-boot.
- Broken kernel, initramfs or rootfs
If the upgrade_available variable is set, u-boot counts the number of
consecutive boots via the bootcount variable. If the bootcount exceeds
the bootlimit variable, u-boot starts the altbootcmd instead of the
bootcmd. Previously, this logic was bypassed by assigning the regular
bootcmd to altbootcmd. Now, the altbootcmd is used to revert to the
previous partition when the bootlimit is exceeded.
The netdev variable is changed to eth0 by default. This is what the FEC
driver uses on Capricorn boards. For devices with switches and DSA
subsystems in use, the netdev should be set accordingly by additional
logic in the environment or u-boot code. This is not part of this commit.

And than the board code does not run, and fallback never

When using a fixed 1.8V regulator for vqmmc (indicated by vs18_enable),
attempting to change the voltage produces spurious errors since the
regulator cannot be adjusted. The driver currently attempts the voltage
change, receives -ENOSYS from the regulator subsystem, and reports:
Setting to 1.8V error: -38
esdhc_set_voltage error -5
Fix this by checking vs18_enable early in esdhc_set_voltage() and
returning -ENOTSUPP for all voltage switch requests, not just 3.3V.
This prevents unnecessary regulator operations and eliminates the
error messages when the hardware is correctly configured with a fixed
1.8V supply.
