IMX53 EVK unable to find /dev/mmcblk0p1

[AnkurMaheshwari]

Hi,

I am getting follwing prints when i am trying to boot filesystem from MMC partition and it gets stuck there itself.

mxc input touchscreen loaded
mxc_rtc mxc_rtc.0: setting system clock to 1970-01-01 01:07:00 UTC (4020)
Waiting for root device /dev/mmcblk0p1...

IF i remove 'rootwait' from the kernel command line argument, then its doesn't shows that kernel is not able to find /dev/mmcblk0p1.

I have used kernel downloaded from Freescale site and kernel compiled by me with surely MMC support enable, but still I am getting this problem.

Any one has idea how can i further debug

In the kernel logs mmc0 and mmc1 controller are detected, but doesn't show mmcblock details,
