Pull request for UEFI sub-system for efi-2020-04-rc4 (2)

In Linux next-20200228 patches have been merged to load an initial ramdisk
using an EFI_LOAD_FILE2_PROTOCOL provided by the firmware. See commit
ec93fc371f01 ("efi/libstub: Add support for loading the initrd from a
device path"). The idea behind it is that the firmware should be
responsible for validating the initrd in a secure boot setup.

This pull-request comprises a patch series which let's U-Boot provide an
initial implementation of the EFI_LOAD_FILE2_PROTOCOL providing the initrd.

UniPhier SoC updates for v2020.04 (3rd)

 - Enable ADMA and HS400 for the eMMC driver on 64-bit SoCs

 - Add some convenient environment variables to handle SD card

 - Sanitize the NAND controller reset sequence and its WP handling

 - Sync DT with Linux

The compatible string "i2c-eeprom" is U-Boot own compatible, which
has never been approved by the DT community. "u-boot,i2c-offset-len"
is also a U-Boot own hack.

Linux adds "atmel,*" as generic compatibles, and U-Boot also followed
it by commit d7e28918 ("i2c_eeprom: Add reading support").

The U-Boot own hack is no longer needed. Just sync with Linux.

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.

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.

- Fix the watchdog on mpc8xx platforms

Commit 06985289 ("watchdog: Implement generic watchdog_reset()

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.

Commit f3729ba6 ("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 b3134ffb
("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.
