There is no "memory" node in my .dts file, so it's inheriting the
default "memory { device_type = "memory"; reg = <0 0>; };" from
skeleton.dtsi. I add memory in my board.c file:
static int kosagi_novena_mem_init(void)
{
/* Pull out RAM capacity, which was stored here in lowlevel.c */
arm_add_mem_device("ram0", 0x10000000, readl(MX6_SRC_BASE_ADDR +
0x20));
return 0;
}
mem_initcall(kosagi_novena_mem_init);
