* 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)
