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.
