- Update abuild.sh so it will rebuild successfull builds
- Move pci_set_method out of hardwaremain.c - Re-add debugging name field but only include the CONFIG_CHIP_NAME is enabled. All instances are now wrapped in CHIP_NAME - Many minor cleanups so most ports build. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1737 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
