* Patch by Michael Bendzick, 30 Aug 2004:
- Improve platform.S code for omap1510inn that detects whether code
is running from SDRAM or not. Patch allows SDRAM to be configured
if code is running out of SRAM at 0x20000000.
* Patch by Frederick Klatt, 30 Aug 2004:
Add support for the Wind River SBC8540/SBC8560 boards
