677 of a misnomer as it includes non-spinning media such as flash (as
678 used in MMC and USB sticks). Partitions provide a way for a disk
679 to be split up into separate regions, with a partition table placed
680 at the start or end which describes the location and size of each
681 'partition'. These partitions are typically uses as individual block
682 devices, typically with an EXT2 or FAT filesystem in each. This
683 option enables whatever partition support has been enabled in
684 U-Boot to also be used in SPL. It brings in the code in disk/.
