Another question - is this setup something that will need to be done
differently for different boards using the mv64x60, or is the same
setup needed for all applications of the mv64x60?

I expect that the setup will be done the same for all of the boards
that need it.  Not all of the boards will need it, though.  It depends
on their firmware.  The config code is filling the gap between what the
firmware should have done and what the kernel drivers require (i.e.,

allowing the ctlrs to access system memory and pci mem/io space).

I'll clarify the last line: "allowing ctlrs on the bridge to access
system memory, allowing the cpu to access pci mem/io space, and allowing
pci devices to access system memory via pci mem reference."
