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.

25 help
26 Enable this for base partition support in SPL. The required
27 partition table types shold be enabled separately. This adds a
28 small amount of size to SPL, typically 500 bytes.

120 Specify the number of partition entries in the GPT. This is
121 meant to allow less than the standard specifies for devices
122 that might need to place their first-stage bootloader in the
123 middle of a regular GPT.
124
125 If unsure, leave at 128 entries, which is the standard
126 number.

132 help
133 Specify an earliest location (in bytes) where the partition
134 entries may be located. This is meant to allow "punching a
135 hole into a device" to create a gap for an SPL, its payload
136 and the U-Boot environment.
137
138 If unsure, leave at 0 (which will locate the partition
139 entries at the first possible LBA following the GPT header).
