Author: mcayland

New Revision: 1233
URL: http://tracker.coreboot.org/trac/openbios/changeset/1233

Log:
prep: Add support for detection of i82378 ISA bridge

Here we simply allow the ISA bridge to be detected during PCI bus enumeration
and implement a stub callback so that devices can be added later.
