o) Reset and configure the bus from scratch rather than expecting U-Boot to
do it for us. Values and configuration from Linux, U-Boot and comments
in the Cavium Simple Executive sources.
o) Do a resource assignment and bus numbering pass in the absence of a PCI
BIOS or firmware that will do it for us.
XXX This has to be the third or fourth instance of this in FreeBSD and
it would be nice to have it become part of the PCI bus driver itself,
like it is on Linux.
o) Fix interrupt mapping for and adjust bus configuration for the Lanner
MR-955, based on information provided by Lanner.
