 Hi Jagannadha,

  Hi,
 
  I need some help on mmc driver development on u-boot.
 
  Few questions:
  1. is mmc framework in u-boot supports all type of card interfaces
  like SD, MMC, and eMMC

 Yes there is a generic framework for MMC. - ./drivers/mmc/ {mmc.c}

  2. If I write a driver do I need to develop the common driver for all
  or a separate drivers for individual cards.

 This is a generic framework. Normally you only need to write MMC controller
 specific code to use it.

  3. Is there any drivers in current u-boot drivers/mmc have individual
  card interfaces support (SD  MMC  eMMC)

 AS fair as I know there aren't any special drivers for any particular 
 vendor.

  4. is there any drivers in
  current u-boot driver/mmc  for common card intefaces (SD | MMC |
 eMMC)

 Yes, you can refer to mmc.c
 One good example is the sdhci.c code which serves for SD cards and eMMC
 (at least for Samsung).

 
  Request for help.
 
  Thanks,
  Jagan.
