eMMC devices have hardware partitions such as user, boot0, and boot1.
Allow these names to be displayed when reading the mmc PARTITION_CONFIG
field via 'mmc partconf'. Additionally allow a name to be specified when
setting the PARTITION_CONFIG.
Before:
u-boot=> mmc partconf 2 1 1 0 && mmc partconf 2
EXT_CSD[179], PARTITION_CONFIG:
BOOT_ACK: 0x1
BOOT_PARTITION_ENABLE: 0x2

Shouldn't these be 'gp' partitions here ?
He Marek,
Do you mean that 3-6 should be named 'gp1', 'gp2' etc? I couldn't find
if those values were possible or have meaning.
Yes, General Purpose eMMC hardware partitions.
