- Rename chip_config chip_operations throughout the tree - Fix Config.lb on most of the Opteron Ports - Fix the amd 8000 chipset support for setting the subsystem vendor and device ids - Add detection of devices that are on the motherboard (i.e. In Config.lb) - Baby step in getting the resource limit handling correct, Ignore fixed resources - Only call enable_childrens_resources on devices we know will have children For some busses like i2c it is non-sense and we don't want it. - Set the resource limits for pnp devices resources. - Improve the resource size detection for pnp devices. - Added a configuration register to amd8111_ide.c so we can enable/disable individual ide channels - Added a header file to hold the prototype of isa_dma_init - Fixed most of the superio chips so the should work now, the via superio pci device is the exception. - The code compiles and runs so it is time for me to go to bed. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1698 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
