Hello Ram,

Thanks for the information.

  Xilinx is using "SD2.0/SDIO2.0/MMC3.31 AHB Host Controller"
     APM is using "SD3.0/SDIO3.0/eMMC4.41 AHB Host Controller"
   Sigma is using "SD3.0/SDIO3.0/eMMC4.4 AHB Host Controller"
Rockchip is using ? (Shawn could you specify exactly which IP you use?)

And it looks like Arasan is using different revision numbers for
every documentation they have.

The "SD3.0/SDIO3.0/eMMC4.4 AHB Host Controller" doc I have is
at rev number 6.0, dated 2010-02-19.

Regards.
