Operating Systems that get hibernated expect all non-boot-time allocations
to be identical before and after hibernation.
In edk2, we create pools and allocate pages starting from the highest

Now that we have a framework available to set memory ranges for
allocations that break hibernation if they move, let's push them
to their own respective memory ranges. This way, they will be
unaffected by boot time data allocation changes and we can thus
still resume hibernated systems.

Hi Alex,
This feature is already available from the DXE Core using the
MemoryTypeInformation and was
specifically added to support hibernation use case.
There is an optional HOB that is passed into DXE Core that can provide bin
sizes for any supported memory types. Not just Runtime and ACPI.

As edk2 design, any new boot options should be put at the end of BootOrder
because these are NEW . That means system should "append" BootOrder instead of
