Hi Arnd,

I like this idea very much and welcome the timing. After the longer than
expected XUSB detour I was going to look at PCI next. Making the driver
work on both 32-bit and 64-bit ARM is the first thing that needs solving
but once that's in place it should be fairly trivial to add support for
Tegra X1 on top.

From a quick glance I think this series is a really good starting point.
I had a couple of questions, but I'll ask them as replies to each patch
for context.
