Hi,
It appears that the import of the ehci code to spice has completely lost the development history and code contributions - from the original version by Mark Burkley through the work I've done on it. Would you mind pulling in the patch history instead of just the final code?
I've first tried to rebase the ehci branch to latest master exactly to keep the history. Was quite messy with lots of conflicts though, so I gave up. For review & upstream merge having the whole history isn't that helpful anyway.
cheers, Gerd
