This commit adds the missing EFI_TCG2_PROTOCOL selftest
and Measured Boot selftest in lib/efi_selftest.

This selftest includes PE/COFF image measurement test, some PCR values are
different in each architecture. With that, this commit also adds pre-built
versions of lib/efi_selftest/efi_miniapp_file_image_exit.c for PE/COFF
image measurement test for 32-bit arm, arm64, ia32, x86_64, riscv32 and
riscv64. Prebuilding avoids the problem of reproducible builds.

The current EFI video driver only works when running in the stub. In that
case the stub calls boot services (before jumping to U-Boot proper) and
copies the graphics info over to the efi table. This is necessary because
the stub exits boot services before jumping to U-Boot.

The app maintains access to boot services throughout its life, so does not
need to do this. Update the driver to support calling boot services
directly.

Enable video output for the app. Note that this uses the
EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa.

A sample qemu command-line for this case is:

   qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd
   -drive id=disk,file=try.img,if=none,format=raw -nic none

Most modern platforms use 64-bit EFI so it is useful to have a U-Boot app
that runs under that. Add a (non-functional) build for this.

Note that --whole-archive causes the gcc 9.2 linker to crash, so disable
this for now. Once this is resolved, things should work.

For now, avoid mentioning the documentation for the 64-bit app, since it
does not work.

Most EFI implementations use 64-bit but U-Boot only supports running as
a 32-bit app at present. While efi-x86_payload64 does boot from 64-bit
UEFI it immediately changes back to 32-bit before starting U-Boot.

In order to support a 64-bit U-Boot app, update the Kconfig to add an
option for 32/64 bit. Update the prompt for the existing option so it is
clear it relates to the stub. Move both up to just under the choice that
controls them, since this looks better and the menu.

Use CONFIG_EFI_APP in the Makefile instead of CONFIG_TARGET_EFI_APP,
since the latter is specific to a single target and we will have two.

Memory size is set to 32MB for now so that it can run on qemu without
increasing the default memory size. We may need to increase the default
later.

It is quite complicated to run U-Boot on QEMU since we have four
different builds and they must use different versions of qemu and the

Add a script to help. It requires U-Boot itself to be built. Once that
is done you can use this script to build an image for use with qemu and

When building a system that has both TPL and SPL_OS_BOOT, code which
tests for CONFIG_SPL_OS_BOOT will be built and enabled in TPL, which is
not correct.  While there is no CONFIG_TPL_OS_BOOT symbol at this time

- Improved sysreset/watchdog uclass integration (Samuel)

Instead of hardcoding the watchdog for reset, and the PMIC for poweroff,
use the sysreset framework to manage the available poweroff/reset
backends. This allows (as examples) using the PMIC to do a cold reset,
and using a GPIO to power off H3/H5 boards lacking a PMIC. Furthermore,
it removes the need to hardcode watchdog MMIO addresses, since the
sysreset backends can be discovered using the device tree.

The sysreset uclass unconditionally provides a definition of the
reset_cpu() function. So does the sunxi board code. Fix the build with
SYSRESET enabled by omitting the function from the board code in that
case. The code still needs to be kept around for use in SPL.

Signed-off-by: NSamuel Holland <samuel@sholland.org>
Reviewed-by: NStefan Roese <sr@denx.de>

Currently, the wdt_reboot driver always gets its watchdog device
reference from an OF node. This prevents selecting a watchdog at
runtime. Move the watchdog device reference to the plat data, so
the driver can be bound with the reference pre-provided. The
reference will still be acquired from the OF node if it is not
already provided.
