Well, everyone does. And that's how FOSS works -- you scratch your own itch by sending a patch, thus helping everyone else ;-) And hey, my boards don't have caches enabled (yet) so this is low-prio for me. Sure, if someone has this as a high-prio thing, patch is very welcome :) > > Tom > > > > Thanks, > > > > > > Tom > > > > > > > > Tom > > > > > > > > > > > > I would have to merge lots of changes from "denx-uboot-tegra" > > > > > > > to make it working for "u-boot-usb.git" master branch. > > > > > > > I can send the adapted patch if it's needed. > > > > > > > > > > > > The problem I see is that there are important USB patches in > > > > > > mainline, though they are not in -tegra.
