Define * GRUB_EFI_PERSISTENT_MEMORY (UEFI memory map type 14) per UEFI 2.5 * GRUB_MEMORY_PERSISTENT (E820 type 7) per ACPI 3.0 * GRUB_MEMORY_PERSISTENT_LEGACY (E820 unofficial type 12) per ACPI 3.0 and translate GRUB_EFI_PERSISTENT_MEMORY to GRUB_MEMORY_PERSISTENT in grub_efi_mmap_iterate(). Includes * adding the E820 names to lsmmap * handling the E820 types in make_efi_memtype() Suggested-by: Vladimir 'φ-coder/phcoder' Serbinenko <phcoder@gmail.com> Suggested-by: Andrei Borzenkov <arvidjaar@gmail.com>
