U-Boot does not yet have SPL code to initialize the DDR controller on the Allwinner D1 - So instead package the sun20i-d1-spl bootloader, which is based on boot0 from the Allwinner BSP with some modifications to build it separately from the BSP and boot mainline U-Boot as explained on the linux-sunxi wiki: https://linux-sunxi.org/Allwinner_Nezha Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
