ARM: AM43xx: EPOS_EVM: Add support for LPDDR2 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.

am33xx: refactor emif4/ddr to support multiple EMIF instances The AM33xx emif4/ddr support closely matches what is need to support TI814x except that TI814x has two EMIF instances. Refactor all the emif4 helper calls and the config_ddr() init function to use an additional instance number argument. Signed-off-by: Matt Porter <mporter@ti.com> Reviewed-by: Tom Rini <trini@ti.com>
