Now this is something I was hoping for :-) I=E2=80=99ll tidy things up next week and I=E2=80=99ll send the initial = dirty patches over to you only (for now) if it=E2=80=99s ok with you? I=E2=80=99ve hacked on top of the rt305x support that=E2=80=99s in the = tree for now, but in a mt762x directory and there are still a lot of = leftovers from rt305x, but at least the thing boots and goes multiuser = albeit on a single core right now :-) Please let me know if this works for you.
