Hi Tony,
Any comments on this patch?
I wonder if I should keep sending fixes/improvements for board-igep0020.c
I already sent an initial Device Tree support for IGEP boards [1] and
Benoit told me he is going to queue for 3.9. But still doesn't support
many peripherals found on these boards because they still don't proper
DT support, for instance NAND and Ethernet need the GPMC bindings
patches that haven't hit mainline yet.
So, it seems I will have to keep working on the board file until it
can be completely deprecated.
Thanks a lot and best regards,
Javier
