Hi All,
I was a bit hasty in providing the patch. Given patch solves u-boot
stuff, but Linux kernel still has some trouble. I am providing second
version of this patch which takes care of start address also. This fixes
Linux kernel issue.
Please ignore this version.
Sorry,
Tanmay

If start of any DRAM bank is greater than total DDR size, remaining
DDR bank sizes were left un-initialized in dram_init function. This
could break other functions who uses array 'gd->bd->bi_dram'.Kirkwood
network driver is one example.
