- 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 git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1200 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
