Hello!
Is there any special support needed for 3621, though?
My understanding is that's just 3630 without a "phone" part?
The .29 kernel they had only added is_omap3621 stuff that's not
called anywhere, but smartreflex code (I guess that's might be
useful to add too of course).
I know about the new code drop is coming, but I don't
expect there to be any basic stuff changes (and this board file
is coming pretty barebones right now), besides I am not so
optimistic to actually expect this patch to be merged right away,
but I am already gathering valuable feedback. ;)
BTW I saw in the archives that you are also working a port,
do you have your tree hosted anywhere?
Bye,
Oleg
