AM4372 EPOS EVM has 1GB LPDDR2(Part no: MT42L256M32D2LG-25 WT:A) Adding LPDDR2 init sequence and register details for the same. Below is the brief description of LPDDR2 init sequence: -> Configure VTP -> Configure DDR IO settings -> Disable initialization and refreshes until EMIF registers are programmed. -> Program Timing registers -> Program PHY control and Temp alert and ZQ config registers. -> Enable initialization and refreshes and configure SDRAM CONFIG register -> Wait till initialization is complete and the configure MR registers.
