Subject: [PATCH] disk: dos: Add all options for EFI System Partitions
The EFI spec states that the ESP can be any of FAT12/16/32 but for
compatibility doesn't necssarily require the partition to be the
EFI partition table ID of 0xef. A number of arm devices will not
find their firmware on a FAT partition with an ID of 0xef so also
allow the original FAT12/16/32 partition IDs as they are also
permissable for an ESP.
