Adding support for OMAP4430 SDP board based on the TI OMAP4430 SOC.
TI OMAP4430 is an SOC based on ARM Cortex-A9 cpu.
OMAP4430 SDP is a reference board based on OMAP4430.
This patch adds minimum support for booting the board.
OMAP4430 SDP does not support XIP. U-boot is loaded to SDRAM with the help of
another small bootloader running from SRAM. U-boot currently relies on this
bootloader for clock, mux, and SDRAM initialization.
This will change when OMAP4430 Configuration Header(CH) is attached
to u-boot. CH is a feature by which ROM code can be made to intialize the
clocks and SDRAM and to copy u-boot directly into SDRAM from a non-XIP device.
More support such as MMC, ethernet etc will be added in subsequent patches.
