fc35d7e1b1 x86: cpu_x86: Make cpu_x86_get_count() non-static
The function cpu_x86_get_count() is also useful for other modules.
Make it non-static and add a prototype + description.

6301615e54 doc: Chromebook Coral: Fix typo for "Top of CAR region"
The value for "Top of CAR region" should be fefc0000, not
fefc000. This matches the Kconfig default values, as
SYS_CAR_ADDR and SYS_CAR_SIZE are 0xfef00000 and 0xc0000
respectively.

5a9d7f9c91 x86: p2sb: Drop 'apl' prefix
Drop the Apollo Lake prefix 'apl' from the functions, types and
variables in the P2SB driver.

The P2SB is not Apollo Lake specific, and as such it was moved in
commit 2999846c11 ("x86: Move P2SB from Apollo Lake to a more generic
location") from the Apollo Lake folder to the intel_common folder.

720f9e1fdb serial: ns16550: Move PCI access from ofdata_to_platdata() to probe()
Currently the ofdata_to_platdata() method calls dev_read_addr_pci(),
which potentially accesses the parent PCI bus. If this happens before
the parent PCI bus is probed the resulting address will be wrong.

This behavior was triggered by commit 82de42fa14 ("dm: core:
Allocate parent data separate from probing parent").

According to a comment in drivers/pci/pci-uclass.c [1] accessing
the PCI parent bus in ofdata_to_platdata() is not allowed, and the
access should be moved to the probe() function.

Move the call to dev_read_addr_pci() and the related handling of the
'addr' value from the ofdata_to_platdata() to its own function,
which is then called from the probe() method.

While moving the code, the comment /* try Processor Local Bus device
first */ was dropped. It was initially added with commit 3db886a5bf
("serial: ns16550: Support ns16550 compatible pci uart devices") and
later made obsolete with commit 33c215af4b ("dm: pci: Add a function
to read a PCI BAR").

[1] Comment in drivers/pci/pci-uclass.c:
"A common cause of this problem is that this function is called in the
ofdata_to_platdata() method of @dev. Accessing the PCI bus in that
method is not allowed, since it has not yet been probed. To fix this,
move that access to the probe() method of @dev instead."

479ab6c17e efi_selftest: add selftests for loadfile2 used to load initramfs
Provide a unit test loading an initial ramdisk using the
EFI_LOAD_FILE2_PROTOCOL. The test is only executed on request.

An example usage - given a file image with a file system in partition 1
holding file initrd - is:

* Configure the sandbox with

  CONFIG_EFI_SELFTEST=y
  CONFIG_EFI_LOAD_FILE2_INITRD=y
  CONFIG_EFI_INITRD_FILESPEC="host 0:1 initrd"

* Run ./u-boot and execute

    host bind 0 image
    setenv efi_selftest load initrd
    bootefi selftest

This would provide a test output like:

    Testing EFI API implementation

    Selected test: 'load initrd'

    Setting up 'load initrd'
    Setting up 'load initrd' succeeded

    Executing 'load initrd'
    Loaded 12378613 bytes
    CRC32 2997478465
    Executing 'load initrd' succeeded

Now the size and CRC32 can be compared to the provided file.

ec80b4735a efi_loader: Implement FileLoad2 for initramfs loading
Following kernel's proposal for an arch-agnostic initrd loading
mechanism [1] let's implement the U-boot counterpart.
This new approach has a number of advantages compared to what we did up
to now. The file is loaded into memory only when requested limiting the
area of TOCTOU attacks. Users will be allowed to place the initramfs
file on any u-boot accessible partition instead of just the ESP one.
Finally this is an attempt of a generic interface across architectures
in the linux kernel so it makes sense to support that.

The file location is intentionally only supported as a config option
argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security.
Although U-boot is not responsible for verifying the integrity of the
initramfs, we can enhance the offered security by only accepting a
built-in option, which will be naturally verified by UEFI Secure Boot.
This can easily change in the future if needed and configure that via ENV
or UEFI variable.

7e00e907f5 watchdog: Don't select CONFIG_WATCHDOG and CONFIG_HW_WATCHDOG at the same time
Commit 06985289d4 ("watchdog: Implement generic watchdog_reset()
version") introduced an automatic selection of CONFIG_WATCHDOG by
CONFIG_WDT. But for boards selecting CONFIG_HW_WATCHDOG, like
boards have a powerpc 8xx, CONFIG_WATCHDOG shall not be selected
as they are mutually exclusive.

Make CONFIG_WATCHDOG dependent on !CONFIG_HW_WATCHDOG

a68256074f watchdog: mpc8xx: Revert the 8xx watchdog back to CONFIG_HW_WATCHDOG
Commit f3729ba6e7 ("watchdog: mpc8xx_wdt: Watchdog driver and macros
cleanup") switched the watchdog to CONFIG_WATCHDOG. But this is not
compatible with the 8xx because it starts the watchdog HW timer at
reset and must be serviced from the very beginning including while
U-boot is executed in the firmware before relocation in RAM.

Select CONFIG_HW_WATCHDOG and make hw_watchdog_reset() visible.

Meanwhile, finalise the cleanup of arch/powerpc/cpu/mpc8xx/Kconfig by
removing the lines put in comment in that commit, and also remove
again the selection of CONFIG_MPC8xx_WATCHDOG which was removed by
that commit and brought back by mistake by commit b3134ffbd9
("watchdog: Kconfig: Sort entry alphabetically")

Note that there was an 'imply WATCHDOG' in the original commit but
it disappeared in the Kconfig alphabetical sorting, so no need to
remove it here.

means FORCE_LINK_GOOD is already setup. Origin code was doing write but the
new code is doing read/modify/write and keep this bit untouched. That's why
ethernet stop to work.
The patch is cleaning this bit when PHYCR value is composed.
