Since there is no net option in our board, we cant check this.

in our board, the ram starts from 0xa0000000, and is of 32 MB.
while creating the uImage, the load address and entry point as 0xa0008000,
and we are loading the image from IDE device to the RAM as,

$diskboot 0xa0001000 0:1

and then,
 $bootm 0xa0001000 to boot from that location.

We are able to get the uImage header information properly,
but after the "Starting kernel", it is restarting, with "data abort"

We have checked the contents of RAM, using md, it is properly copied
at 0xa0001000.
then, after restarting, we cheked the contents at 0xa0008000, at the
both the locations,
the kernel is proper.
