This general MMDC driver adds basic support for Freescale MMDC (Multi Mode DDR Controller). Currently MMDC is integrated on ARMv8 LS1012A SoC for DDR3L, there will be a update to this driver to support more flexible configuration if new features (DDR4, multiple controllers/chip selections, etc) are implimented in future. Meantime, reuse common MMDC driver for LS1012ARDB/LS1012AQDS/ LS1012AFRDM. Signed-off-by: Shengzhou Liu <Shengzhou.Liu@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
