Have strange DRAM size detection on CB1 with 2x GT8UB256W DDR chips:
spl & uboot from original nand detects 1GiB, but board has only 512MiBs
Hand-builded generic u-boot-2014.10 with Cubieboard_config and a10/cubieboard_512.fex from sunxi-boards
gives the same result.
Please help how to force DRAM size on uboot (and maybe kernel) build.
