EFI calls can made directly on ARM, so the function pointers
are directly invoked. This allows types to be checked at
compile time, so here we ensure that the parameters match
the function signature.

Make efi_free() safely callable with size of 0, similar to free() being
callable with NULL pointers.
Remove size checks that this makes redundant. This also avoids some
size checks in the ARM EFI stub code that will be added as well.

The existing code could fail to allocate depending
on allocation size, as although repeated allocation
attempts were made, none were guaranteed to be page
aligned.

The handle_cmdline_files now takes the option to handle as a string,
and returns the loaded data through parameters, rather than taking
an x86 specific setup_header structure. For ARM, this will be used
to load a device tree blob in addition to initrd images.
Signed-off-by: Roy Franz roy.fr
Rename variables to be not initrd specific, as now the function
loads arbitrary files.

Rename them to be more similar, as low_free() could be used to free
memory allocated by both high_alloc() and low_alloc().
high_alloc() - efi_high_alloc()
low_alloc() - efi_low_alloc()
low_free() - efi_free()

Dave - here is an updated patch for head.S, I'm still working on the
rest. I will make the EFI stub depend on !CPU_ENDIAN_BE32 to make the
stub LE only for now. I think I have addressed the rest of your
comments in head.S in the patch below. I will send a complete new
series once I have the
