u-boot-1.1.6.
my sdram is 512MB, with CS0_BNDS,DDRLAWAR0,DDRLAWBAR0 modified, 256MB of
512MB sdram can work perfectly.
Then, I defined CONFIG_VERY_BIG_RAM, 512MB can be recognized, but, I can
only read and write 256MB, fault occurred when address move across 256MB.
besides CONFIG_VERY_BIG_RAM, what else should I do to support big sdram?
Thanks!

Suggest you use the latest u-boot as base, due to the u-boot/kernel
interface has much change since 1.1.6.

Please check the DDR controller configuration according to your board.
Did the ROW/COL address setup correctly?
