Here is a suprisingly small set of patches that enable Asus TF300T tablet
to boot and have all cores available. TF300T is one of a consumer devices

This is very cool! How did you debug it, or did it work on the first
try? :) I have a TF201 myself, probably quite similar to this, might be
worth a try.
This series is an arch-dependent part. TF parts were extracted from ASUS's
GPL code dump. The rest being driver code - a work in progress - is
available in branch tf300t at:
https://rere.qmqm.pl/git/linux
This URL doesn't work for me at least in the browser, but
https://rere.qmqm.pl/git/?p=linux;a=summary works.
Regarding the USB device mode - yes, there are several drivers for
roughly the same hardware. It would be good to get both host and device
mode with the same driver so that we could have OTG support.
Cheers,
