TI OMAP3 SDP3430: Initial Support

Start of support of
Texas Instruments Software Development Platform(SDP)
for OMAP3430 - SDP3430

Highlights of this platform are:
Flash Memory devices:
	Sibley NOR, Micron 8bit NAND and OneNAND
Connectivity:
	3 UARTs and expanded 4 UART ports + IrDA
	Ethernet, USB
Other peripherals:
	TWL5030 PMIC+Audio+Keypad
	VGA display
Expansion ports:
	Memory devices plugin boards (PISMO)
	Connectivity board for GPS,WLAN etc.
Completely configurable boot sequence and device mapping
etc.

Support default jumpering and:
 - UART1/ttyS0 console(legacy sdp3430 u-boot)
 - UART3/ttyS2 console (matching other boards,
		 and SDP HW docs)
 - Ethernet
 - mmc0
 - NOR boot

Currently the UART1 is enabled by default.  for
compatibility with other OMAP3 u-boot platforms,
enable the #define of CONSOLE_J9.

Conflicts:

	Makefile

Fixed the conflict with smdkc100_config by moving omap_sdp3430_config
to it is alphabetically sorted location above zoom1.
