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 */
