Subject[PATCH 0/2][RFC] Introduce "efi_fake_mem_mirror" boot option
Date
UEFI spec 2.5 introduces new Memory Attribute Definition named
EFI_MEMORY_MORE_RELIABLE which indicates which memory ranges are
mirrored. Now linux kernel can recognize which memory ranges are mirrored
by handling EFI_MEMORY_MORE_RELIABLE attributes.
However testing this feature necesitates boxes with UEFI spec 2.5 complied
firmware.

This patchset introduces new boot option named "efi_fake_mem_mirror".
By specifying this parameter, you can mark specific memory as
mirrored memory. This is useful for debugging of Memory Address Range
Mirroring feature.

Taku Izumi (2):
efi: Add EFI_MEMORY_MORE_RELIABLE support to efi_md_typeattr_format()
x86, efi: Add "efi_fake_mem_mirror" boot option
