Running grub2-mkconfig complains with
grub2-probe: error: cannot find a device for / (is /dev mounted?).
/dev is mounted and looks valid. If I point grub2-probe to / I get the
same error, whereas if I point it to the /dev device mounted to it, it
exits normally.
I suspect grub2-probe is confused
The EFI page definitions and macros are generic and should not be confined
to atm64 headers - so move to efi/memory.h.
Also add EFI_PAGE_SIZE macro.
Update loader sources to reflect new header location.

There are several implementations of this function in the tree.
Add a central version in grub-core/efi/mm.c.

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.

Expose a new function, grub_efi_allocate_pages_real(), making it possible

Make grub_efi_allocate_pages() a consumer of the new function,
maintaining its old functionality.
Also delete some left-around

There is nothing ARM64 (or even ARM) specific about the efi fdt helper
library, which is used for locating or overriding a firmware-provided
devicetree in a UEFI system - so move it to loader/efi for reuse.

The 32-bit arm efi port now shares the 64-bit linux loader, so delete

This in turn leaves the grub-core/kern/arm/efi/misc.c unused, so

The 32-bit arm Linux kernel is built as a zImage, which self-decompresses
down to near start of RAM. In order for an initrd/initramfs to be
accessible, it needs to be placed within the first ~768MB of RAM.
The initrd loader built into the kernel EFI stub restricts this down to
512MB for simplicity

grub-installer is part of the Debian installer, and is not part of GRUB.

This assumes that all CPUs supporting EFI have 4K pages. What if some of

Looks good. But out of context the name is not descriptive enough. Can we
add a comment near declaration to clarify what this functions is for?
