+ * This is the main Quark Memory Reference Code (MRC)

+ * These functions are generic and should work for any Quark-based board.

+ * MRC requires two data structures to be passed in which are initialized by

+ *
+ * The basic flow is as follows:
+ * 01) Check for supported DDR speed configuration
+ * 02) Set up Memory Manager buffer as pass-through (POR)
+ * 03) Set Channel Interleaving Mode and Channel Stride to the most aggressive
+ *     setting possible
+ * 04) Set up the Memory Controller logic
+ * 05) Set up the DDR_PHY logic
+ * 06) Initialise the DRAMs (JEDEC)
+ * 07) Perform the Receive Enable Calibration algorithm
+ * 08) Perform the Write Leveling algorithm
+ * 09) Perform the Read Training algorithm (includes internal Vref)
+ * 10) Perform the Write Training algorithm
+ * 11) Set Channel Interleaving Mode and Channel Stride to the desired settings
+ *
+ * DRAM unit configuration based on Valleyview MRC.
