Just how did you want all these different drivers to be built?  You
said you don't want a separate module containing an entire copy of the
ehci core for each arch; you want the core to be shared.  That means
one of two things:

	Build a single monolithic module containing all the drivers.
	This is quite likely to require a large bunch of #ifdefs.

	Build a minimal driver module for each arch, and have the ehci
	core in a single separate module that gets loaded for
	dependency resolution.  This is likely to require a bunch of
	exported symbols.

Which approach are you advocating?
