src/sys/stand/efiboot: efiblock.c version
Log Message:
add basic raidframe support to efiboot.
if raid disklabel or gpt is found, add this partition with
the offset/size adjusted by RF_PROTECTED_SECTORS. note
don't le32toh() the disklabel. if it was wrong-endian, then
getdisklabel() will have swapped it.
ok jmcneill thorpej.
