arch/arm/mach-sunxi/dram_sun8i_a33.c and 1Gb detect as 512Mb on A33.

I have a tablet with 1Gb of ram (two chips),but not u-boot neither kernel detect it (only 512Mb).

Does i need to change something in arch/arm/mach-sunxi/dram_sun8i_a33.c ?

i posta alettronica found this struct in sunxi_dram_init(void) function:

struct dram_para para = {
                 .cs1 = 0,
                 .bank = 1,
                 .rank = 1,
                 .rows = 15,
                 .bus_width = 16,
                 .page_size = 2048,
         };

Thanks
