- Bump MAX_LINKS to 4 I have actually found an i2c bridge that needs this
- Fix the hdama Config.lb to not longer use the link keywords oops, and instead to have it nest everything properly. - Update config.g to not support the link keyword - update config.g to not support northbridge/southbridge/cpu/pmc noise words we can just use chip now. - Remove old link handling from the code - Detect and handle duplicate paths so we generate one device with multiple links git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1685 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
