CONFIG_ENV_VARS_UBOOT_CONFIG, CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and CONFIG_BOARD_LATE_INIT is already set. Adding support to detect the board. These variables are used by findfdt.

Updating the Multiplier and Dividers value for all DPLLs. Safest OPP is read from DEV ATTRIBUTE register. Accoring to the value returned the MPU DPLL is locked. At different OPPs follwoing are the MPU locked frequencies. OPP50 300MHz OPP100 600MHz OPP120 720MHz OPPTB 800MHz OPPNT 1000MHz According to the latest DM following is the OPP table dependencies: VDD_CORE VDD_MPU OPP50 OPP50 OPP50 OPP100 OPP100 OPP50 OPP100 OPP100 OPP100 OPP120 So at different OPPs of MPU it is safest to lock CORE at OPP_NOM. Following are the DPLL locking frequencies at OPP NOM: Core locks at 1000MHz Per locks at 960MHz LPDDR2 locks at 266MHz DDR3 locks at 400MHz

Touching AM33xx files also to get DPLL values specific to board but no functionality difference. Signed-off-by: Lokesh Vutla lokeshvutla@ti.com --- Changes since V2: -> Populated DPLLs data for all OPPs and SYS CLK inputs and the correct values to be read from eFuse.

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.
