am335x_evm: am33xx_spl_board_init function and scale core frequency Add a am33xx_spl_board_init (and enable the PMICs) that we may see, depending on the board we are running on. In all cases, we see if we can rely on the efuse_sma register to tell us the maximum speed. In the case of Beaglebone White, we need to make sure we are on AC power, and are on later than rev A1, and then we can ramp up to the PG1.0 maximum of 720Mhz. In the case of Beaglebone Black, we are either on PG2.0 that supports 1GHz or PG2.1. As PG2.0 may or may not have efuse_sma set, we cannot rely on this probe. In the case of the GP EVM, EVM SK and IDK we need to rely on the efuse_sma if we are on PG2.1, and the defaults for PG1.0/2.0. Signed-off-by: Tom Rini <trini@ti.com>

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.

am335x:Handle worst case scenario for Errata 1.0.24 In Errata 1.0.24, if the board is running at OPP50 and has a warm reset, the boot ROM sets the frequencies for OPP100. This patch attempts to drop the frequencies back to OPP50 as soon as possible in the SPL. Then later the voltages and frequencies up set higher.
