We could (should) probably investigate some other options.  The 8240
Sandpoint had the same challenge, and I followed Cort's example from
the Gemini.....Just do everything in the xxx_pci.c functions.

It used to be the Linux kernel relied heavily on the PCI already
initialized (which is normally OK in a desktop world).  With the number
of "patches" due to desktops not even doing this correctly, I wonder
if we shouldn't find some place to perform this initialization.  The
current "fixup" functions are too late for embedded systems that don't
do anything prior to kernel boot.

I'll experiment with the new Embedded Planet Classic and QSpan II.  If
someone with real PCI knowledge has some suggestions, that would
really help.
