[U-Boot] How to access GP partitions from uboot (2015.04)

[harsha kiran]

Hi!

I have created 4 hw GP partitions on the eMMC (GP1,2,3,4) and formatted with
ext4 fs. I have to read the contents of these partitions from the uboot but
i am not finding them in the mmc part command.

I can see them in the mmc info...
U-Boot# mmc info
Device: OMAP SD/MMC
Manufacturer ID: fe
OEM: 14e
Name: MMC16
Tran Speed: 52000000
Rd Block Len: 512
MMC version 4.4.1
High Capacity: Yes
Capacity: 13.5 GiB
Bus Width: 8-bit
Erase Group Size: 8 MiB
HC WP Group Size: 16 MiB
User Capacity: 13.5 GiB
Boot Capacity: 16 MiB ENH
RPMB Capacity: 128 KiB ENH
GP1 Capacity: 256 MiB
GP2 Capacity: 400 MiB
GP3 Capacity: 256 MiB
GP4 Capacity: 256 MiB

But when i do mmc part i only see the user data partition information..i
dont see the gp partition information

U-Boot# mmc part

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

Part    Start Sector    Num Sectors     UUID            Type
  1     16              31280           00000000-01     0e Boot
  2     31296           28181952        00000000-02     83

Do i have to enable any thing in the config to see them?

Thanks,
Harsha
