Hi all,
This series enabled EFI support to MIPS platform.
Although MIPS is not defined by UEFI specification, there are
quite a few firmware implementations available, including
MIPS-EFI[1] for Loongson-2F, Lemote's proprietary EDK2 implementation
on Loongson-3[2], Kunlun firmware for Loongson-3[3], efiffy[4]
for MIPS Creator CI20 and another mystery EDK implementation shipped
with some Creator CI20 board.
Available applications including gnu-efi, Loongson's GRUB fork[5],
Ventoy[6].
My implementation in U-Boot is aiming to follow conventions made
by other implementations for architecture stuff and remain
compliance with spec for general aspects.
bootefi hello and selftest passed on both 32 and 64 bit system,
gnu-efi, grub and ventoy are tested on mips64el with my pending
platform works. mips32el efi executable from efiffy is tested
as well.
Please review.
Thanks

This looks like riding a dead horse.
