* 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
