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.
