Previous output:
Marvell>>  mmc part

Partition Map for MMC device 1  --   Partition Type: EFI

Part  Start LBA  End LBA
gpt1  0x8C00    0xCBFF
gpt2  0xCC00    0x57BFF
gpt3  0x57C00    0xA2BFF
gpt4  0xA2C00    0xECBFDE

With the patch, the output becomes:
Marvell>> mmc part

Partition Map for MMC device 1  --   Partition Type: EFI

Part            Name            Start LBA       End LBA
 1                 ramdisk      0x00008C00      0x0000CBFF
 2                  system      0x0000CC00      0x00057BFF
 3                userdata      0x00057C00      0x000A2BFF
 4               remaining      0x000A2C00      0x00ECBFDE
