When starting the app, locate all block devices and make them available
to U-Boot. This allows listing partitions and accessing files in
filesystems.
EFI also has the concept of 'disks', meaning boot media. For now, this
is not obviously useful in U-Boot, but add code to at least locate these.
This can be expanded later as needed.
We cannot use printf() in the early stub or app since it is not compiled
in

Typically the bloblist is positioned at a fixed address in memory until
relocation. This is convenient when it is set up in SPL or before
relocation.
But for EFI we want to set it up only when U-Boot proper is running. Add
a way to allocate it using malloc() and update the documentation to cover
this aspect of bloblist.
Note there are no tests of this feature at present, nor any direct testing
of bloblist_init().
This can be added, e.g. by making this option controllable at runtime.

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

OF_HOSTFILE is used on sandbox configs only. Although it's pretty
unique and not causing any confusions, we are better of having simpler
config options for the DTB.
So let's replace that with the existing OF_BOARD. U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

When a test hands on a real board there is no way on the console to obtain

With sandbox we can actually find out that it died and get a signal or

c = os.read(self.fd, 1024).decode(errors='replace')

We get:

BIOS Release Date must be in format mm/dd/yyyy and must be release date.
U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is
generated from current build timestamp.
Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is
better approximation of U-Boot release date than current build timestamp.
Current U-Boot versioning is in format yyyy.mm so as a day choose 01.
Some operating systems are using BIOS Release Date for detecting when was
SMBIOS table filled or if it could support some feature (e.g. BIOS from
1990 cannot support features invented in 2000). So this change also ensures
that recompiling U-Boot from same sources but in different year does not
change behavior of some operating systems.
