[U-Boot] [u-boot] How to configure CONFIG_SYS_INIT_SP_ADDR

Hi,

I am getting compilation issues on v11.12 with CONFIG_SYS_INIT_SP_ADDR. Actually my SD RAM size was 256MB.

Can any one tell me how can I configure this macro?... I have seen a procedure to do while defining this macros on some boards on denx tree

Regards, Jagan.
