I think the area of code that needs investigating is in
arch/arm/cpu/armv7/omap3/sdrc.c
line 82 onwards :-
> u32 get_sdr_cs_size(u32 cs)
> {
> u32 size;
>
> /* get ram size field */
> size = readl(&sdrc_base->cs[cs].mcfg) >> 8;
> size &= 0x3FF; /* remove unwanted bits */
> size <<= 21; /* multiply by 2 MiB to find size in MB */
> return size;
> }

Which I think is set in arc/arm/include/asm/arch-omap3/cpu.h but I don't
understand how the -> stuff works.
I think its line 262 which is wrong but I'm not sure what it should say.
> #define RAMSIZE_128 (0x40 << 8) /* RAM size in 2MB chunks */
