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
