Actually, Spear platform supports up to 1GB of RAM.
The problem is that the ddr driver does not work properly for the 
function get_ram_size when the max size of RAM is passed more than
the supported size on the board. There are random crashes while 
running uboot
The problem is with ddr driver. I have to look into this. 
This commit change is temporary and once the ddr driver problem is 
resolved, it would get back to 1GB
