[PATCH 0/5] beautify EFI memmap logs

It's a pain to analyze EFI memmap logs while debugging, especially to
verify the memory types (an enum) and the memory attributes (a bitmap).
This series renders those columns human-readable, and unifies their
formatting between x86, ia64 and arm64.

Example output with the patchset on arm64 (in a qemu-system-aarch64
guest, booted with Ard's v5 series from edk2-devel ("QEMU_EFI.fd")):

I can't test the series on ia64.

Thanks,

Laszlo Ersek (5):
efi: add macro for EFI_MEMORY_UCE memory attribute
efi: introduce efi_md_typeattr_format()
x86: efi: format EFI memory type & attrs with efi_md_typeattr_format()
ia64: efi: format EFI memory type & attrs with
efi_md_typeattr_format()
arm64: efi: format EFI memory type & attrs with
efi_md_typeattr_format()
