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.

Consider using puts() when you don't need any output formatting.
+#endif /* CONFIG_DISPLAY_BOARDINFO */
...
+#ifdef CONFIG_DISPLAY_CPUINFO
These #defines have never been documented. It seems they are being copied around a lot, but I'm not sure if anybody ever does NOT set these.
I think we should at least document these - or rather drop them everywhere. What do you think?
+{
- printf ("CPU : OMAP4430 ES1.0 \n");
puts()?
And: no spaces after function names please (fix globally!).

Incorrect multiline comment style - in addition, the comment ("start at 16 meg boundary -ends at 1Meg") makes no sense to me.
+#define CONFIG_SYS_MEMTEST_START 0x80000000 +#define CONFIG_SYS_MEMTEST_END (CONFIG_SYS_MEMTEST_START + (1 << 20))
Why would you want to test only such a small fration of your system RAM?

No dead code, please.
