- O2, enums, and switch statements work in romcc
- Support for compiling romcc on non x86 platforms
- new romc options -msse and -mmmx for specifying extra registers to use
- Bug fixes to device the device disable/enable framework and an amd8111 implementation
- Move the link specification to the chip specification instead of the path
- Allow specifying devices with internal bridges.
- Initial via epia support
- Opteron errata fixes
