The arm64 and arm linux kernel EFI-stub support presents pretty much
identical interfaces, so the same linux loader source can be used for
both architectures.
Switch 32-bit ARM UEFI platforms over to the existing EFI-stub aware
loader initially developed for arm64.
This *WILL* stop non-efistub Linux kernels from booting on arm-efi.

Patch-Name: arm-efi-switch-to-arm64-linux-loader.patch
Since ARM platforms do not have a common memory map, add a helper
function that finds the lowest address region with the EFI_MEMORY_WB
attribute set in the UEFI memory map.
Required for the arm64 efi linux loader to restrict the initrd
location to where it will be accessible by the kernel at runtime.

Patch-Name: efi-add-grub_efi_get_ram_base-for-arm64.patch
With upcoming changes to EDK2, allocations of type EFI_LOADER_DATA may
not return regions with execute ability. Since modules are loaded onto
the heap, change the heap allocation type to GRUB_EFI_LOADER_CODE in
order to permit execution on systems with this feature enabled.

Patch-Name: efi-change-heap-allocation-type.patch
Expose a new function, grub_efi_allocate_pages_real(), making it possible
to specify allocation type and memory type as supported by the UEFI
AllocatePages boot service.
Make grub_efi_allocate_pages() a consumer of the new function,
maintaining its old functionality.
Also delete some left-around #if 1/#else blocks in the affected
functions.
