Nice. I was planning on converting bcm2835 to multi-platform in 3.8; I
assume it'll be pretty simple.

Hmmm. I believe the bcm2835 uses DWC OTG. I wonder if the same driver
will work there; USB in particular is a major pain point on the bcm2835...

There are two chunks of code related to that; uncompress.h and
debug-macro.S. Rob/Arnd's multi-platform patches already allowed
debug-macro.S to exist after multi-platform conversion, and my patches
were about adding back support for uncompress.h. Given that the only
reason I cared about uncompress was that Tegra's uncompress.h and
debug-macro.s were closely coupled, and Nicolas Pitre indicated he
thought that was a hack, I've re-written the Tegra code so they aren't
coupled any more (this will be included in 3.8) and so I care much less
about uncompress.h now. Unless anyone really pipes up and says they'd
still like me to pursue uncompress.h in multi-platform, I'm inclined to
drop it.

Thanks! Do note that much of the code I upstreamed was originally
written by others, although I did make quite a few changes during
upstream submission.
