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

91	  Specify the number of partition entries in the GPT. This is
92	  meant to allow less than the standard specifies for devices
93	  that might need to place their first-stage bootloader in the
94	  middle of a regular GPT.
95
96	  If unsure, leave at 128 entries, which is the standard
97	  number.

102	default 0
103	help
104	  Specify an earliest location (in bytes) where the partition
105	  entries may be located. This is meant to allow "punching a
106	  hole into a device" to create a gap for an SPL, its payload
107	  and the U-Boot environment.
108
109	  If unsure, leave at 0 (which will locate the partition
110	  entries at the first possible LBA following the GPT header).
