The GPT functionality really cannot be tested without a block device.   
We could build the disk.raw described in board/sandbox/README.sandbox 
when (CONFIG_UNIT_TEST && CONFIG_CMD_GPT_RENAME) in imitation of the 
file helloworld.efi.   There would be no reason for the size to be as 
large as 1200M, of course.   256KB appears to be the smallest usable 
size for 4 partitions (although trying to partition a 16 KB raw object 
with gdisk produces entertaining results).

To create this object for testing, we could use a subdirectory like 
lib/efi_loader, but maybe doing so in test/ makes more sense?  If the 
build system did create the object, then we could modify 
board/sandbox/README.sandbox to so indicate.   Then the test should go 
in test/py/tests presumably.

Thanks for feedback,
Alison
