This does the following:
cd coreboot/src/southbridge svn mv i82801ca i82801cx svn mv i82801dbm i82801dx svn mv i82801er i82801ex svn copy i82801xx i82801bx svn mv i82801xx i82801ax Plus, fixing up the filenames in these directories and the romstage.c and Kconfig files of the mainboards using those drivers. Plus, switching the thomson ip1000 and rca rm4100 to the i82801dx driver. There's a lot more to be done, like - adding device IDs for the ICH3 and newer drivers that have been kept in i82801xx so far - drop the additional parts support from the ax and bx drivers.
