    Subject[PATCH 03/10] efi: Make EFI_MEMORY_ATTRIBUTES_TABLE initialization common across all architectures
    Date
    From: Sai Praneeth <sai.praneeth.prakhya@intel.com>

    Since EFI_PROPERTIES_TABLE and EFI_MEMORY_ATTRIBUTES_TABLE deal with
    updating memory region attributes, it makes sense to call
    EFI_MEMORY_ATTRIBUTES_TABLE initialization function from the same place
    as EFI_PROPERTIES_TABLE. This also moves the EFI_MEMORY_ATTRIBUTES_TABLE
    initialization code to a more generic efi initialization path rather
    than ARM specific efi initialization. This is important because
    EFI_MEMORY_ATTRIBUTES_TABLE will be supported by x86 as well.
