| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DDR controller 5.2.1 has this erratum A008511 partially fixed. The workaround needs to be adjusted to take advantage of Vref training. This patch enables the training and force output enable to be off. Erratum A009803 requires the controller to be idel before enabling address parity. It was combined with workaround for A008511. With new A008511 flow, this flow needs to be changed to enabling data init (D_INIT) after the address parity is enabled.
