   7           Partition Labels (disklabels) Supported:
   8           Zero or more of the following:
   9           - CONFIG_MAC_PARTITION   Apple's MacOS partition table.
  10           - CONFIG_DOS_PARTITION   MS Dos partition table, traditional on the
  11                                    Intel architecture, USB sticks, etc.
  12           - CONFIG_ISO_PARTITION   ISO partition table, used on CDROM etc.
  13           - CONFIG_EFI_PARTITION   GPT partition table, common when EFI is the
  14                                    bootloader.  Note 2TB partition limit; see
  15                                    disk/part_efi.c
  16           - CONFIG_MTD_PARTITIONS  Memory Technology Device partition table.
  17           If IDE or SCSI support is enabled (CONFIG_CMD_IDE or CONFIG_SCSI)
  18           you must configure support for at least one non-MTD partition type
  19           as well.
