[U-Boot] [PATCH 1/3] x86: efi: payload: Make efi payload build again

[Bin Meng]

Since commit 73c5c39 "Makefile: Drop unnecessary -dtb suffixes",
EFI payload does not build anymore. This fixes the build.

[U-Boot] [PATCH 2/3] x86: efi: payload: Correct BITS_PER_LONG to 32

[Bin Meng]

U-Boot itself as EFI payload is still running in 32-bit mode.
So BITS_PER_LONG should still be 32. This fixes the warnings
when building EFI 64-bit payload.

include/asm-generic/bitops/__fls.h:17:2:
  warning: left shift count >= width of type
	if (!(word & (~0ul << 32))) {

[U-Boot] [PATCH 3/3] x86: qemu: efi: Add two boards for EFI 32-bit and 64-bit payload

[Bin Meng]

This introduces two board defconfig files for generating EFI 32-bit
and 64-bit payloads, to run on QEMU x86 target.

With these in place, hopefully buildman will catch any build error
with EFI payload support on x86.

Great!

By the way I am working on initial 64-bit support and hope to have
patches out in 2-3 weeks. I've run out of time for now unfortunately.

Sorry this patch needs rework as 64-bit payload does not boot. I will
work on a v2.
