The following is the current set of patches so far to support
PBL for the skov-arm9cpu.
The pwm is not really part of this - but it is part of the story.
The patch-set was triggered when someone reported a bug in the
atmel pwm code. The code did not build - so I ported it over.
Now I wanted to boot the target, but at91bootstrap no longer
supports the at91sam9263. So I decided to try to make it work
in barebox. I have tried this before and failed - but it should
be possible...
What I have made is modelled on top of all the great work
for other more modern atmel bouards.
This is an RFC - because the code does not yet work :-(
It fails to mount the SD Card - for reasons I am yet to discover.
Most of the code is attempted to be generic so we can use it
for other targets.
Feedback on the general structure would be nice.
But otherwise just consider this a short status that something
is in the works and I may return to this later - no promises
on the timeframe though.
