This is from the file linux/arch/arm/mach-nds/arch.c.
This is a machine with an optional RAM extension:

static void __init
fixup_nds(struct machine_desc *desc, struct tag *tags,
char **cmdline, struct meminfo *mi)
{
mi->bank[0].start = CONFIG_DRAM_BASE;
mi->bank[0].size = CONFIG_DRAM_SIZE;
mi->bank[0].node = 0;
mi->nr_banks = 1;
#ifdef CONFIG_NDS_ROM8BIT
if (gba_activate_ram()) {
mi->bank[1].start = gba_start;
mi->bank[1].size = gba_length;
mi->bank[1].node = 0;
mi->nr_banks = 2;
}
#endif
}
MACHINE_START(NDS, "Nintendo DS")
