Sort-of. Basically, PowerPC can (and must in some case) build a single
kernel image that can be booted on a variety of platforms. There are at
least 3 platforms coming in now (this Efika is one of them) where that
includes a non-PCI OHCI or EHCI (big endian even) while the same kernel
must also contain the normal PCI OHCI/EHCI driver.

It's generally not a problem as the endian thingy is a runtime bit, and
in general, the whole code allows for this just fine, with, afaik, the
exception of the multiple module_init() bits...

Not that I know. But we could have a cleaner approach. The #include one
dates a bit... we could have for example an ohci-core.ko with the core
bits, and ochi-pci.ko, ohci-patform.ko etc... be separate modules linked
on the first and instanciating it.

I'll have a look and will come up with either solution.
