Subject: * Patch by Steven Scholz, 10 Oct 2003   - Add support for Altera FPGA
 ACEX1K

* Patches by Thomas Lange, 09 Oct 2003:
  - Endian swap ATA identity for all big endian CPUs, not just PPC
  - MIPS only: New option CONFIG_MEMSIZE_IN_BYTES for passing memsize
    args to linux
  - add support for dbau1x00 board (MIPS32)
