The sdram drivers for Rockchip SoCs was all separate, some of the SoCs has similar hardware controller and phy, so we have a change to share the flow and some of the functions between different SoCs. This patch set implement a first version common code based on PX30, other SoCs has similar hardware can migrate to this common code, eg. rk3328 and rk3399 can use this common code.
This patch set also fix some bug for rk3399 by sync code from latest rockchip vendor code.
Changes in v2: - Split the patches into multi smaller patches for easy to maintain, review and test; - Keep the DRAM_ROCKCHIP_DEBUG macro and enable it by default; - Update the rockchip_sdram_size to support sys_reg3;
