This is the re-send and fixed up version of the patch I sent out a few
weeks ago, to be applied against latest linux-mips GIT. Unless somebody
finds something horrible, I think these are ready to go into Greg's tree
and sent on upstream.
Here is the changelog:
* All OTG references are removed and moved to their own patch (which will
be forthcoming soon).
* Fixed up some coding issues with the move from PCI, including the
mapping of EHCI capability and operations registers (causing the bugs
that were posted here).
* Cached the cap register for speed
* Au1200 init and remove routines were in the wrong place
* reboot_notifier was registered twice
