Would this work asis on the MX31 uboot.
I tried making the code work on the MX31 with minor mods ( on some
registers).  Would it work on MX31? I am trying to understand the
hardware better. I had some confusion on the internally generated
clock. This code seems to borrow heavily from the linux api's. So it i
s using the imx_get_perclk2() function as a source of the divder
frequency. Will it work on the imx31. U-boot already has the
mx31_get_ipg_clk() for extracting the clock. Which one should i use
for the SD_MMC_CLOCK? From the data sheet, it seems ipgperclk3() has
to be used for the divider. I am not sure though at this point .

I am not getting a response from the SD card for the OCR  for voltage
validation as a part of the card identification cycle.
Any help will be appreciated.

Thanks,
Alfred,
