3fef0def84 x86: coreboot: Enable VIDEO_COPY
At least on modern machines the write-back mechanism for the frame buffer
is quite slow when scrolling, since it must read the entire frame buffer
and write it back.

Enable the VIDEO_COPY feature to resolve this problem.

3609e1dc5f dts: automatically build necessary .dtb files
When building for a custom board, it is quite common to maintain a
private branch which include some defconfig and .dts files. But to
hook up those .dts files requires modifying a file "belonging" to
upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch
to a newer upstream then often results in a conflict which, while it
is trivial to resolve by hand, makes it harder to have a CI do "try to
build our board against latest upstream".

The .config usually includes information on precisely what .dtb(s) are
needed, so to avoid having to modify the Makefile, simply add the
files in (SPL_)OF_LIST to dtb-y.

A technicality is that (SPL_)OF_LIST is not always defined, so rework
the Kconfig symbols so that (SPL_)OF_LIST is always defined (when
(SPL_)OF_CONTROL), but only prompted for in the cases which used to be
their "depends on".

nios2 and microblaze already have something like this in their
dts/Makefile, and the rationale in commit 41f59f6853 is similar to
the above. So this simply generalizes existing practice. Followup
patches could remove the logic in those two makefiles, just as there's
potential for moving some common boilerplate from all the
arch/*/dts/Makefile files to the new scripts/Makefile.dts.

At present only 4KB of spare space is left in the DTB when building the
EFI app. Increase this to 32KB so there is plenty of space to insert the
binman definition. This cannot be expanded later (as with OF_SEPARATE)
because the ELF image has already been built.

1834c081d3 efi: Add video support to the app
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

144cb06083 x86: edison: Don't take SD card detect pin into consideration
There are two PCB designs in the wild which use the opposite
signaling for SD card detection. This makes U-Boot working
in one case and failing in the other. Quirk this out by
disconnecting SD card detection pin from the PCB by switching
it to mode 3. In the disconnected state the read value is always
the same and inverted to what we are expecting in the code.
