short strings can be used in type parameter of gpt command
to replace the guid string for the types known by u-boot
partitions = name=boot,size=0x6bc00,type=data; \
name=root,size=0x7538ba00,type=linux;
gpt write mmc 0 $partitions
and they are also used to display the type of partition
in "part list" command
Partition Map for MMC device 0 -- Partition Type: EFI
Part Start LBA End LBA Name
