BTW, both at91_dbgu.h and cpu.h are needed for the uncompress.h AT91
file. I need to re-integrate both of them until this feature is
completely generalized with multi-platform. Are you okay with this
modification?

I'm perfectly fine with removing the old setup code as we have the full
DT initialization in place.
This setup code didn't prove it had added any benefit in comparison with
the usual DT initialization process. Code is much more simpler and clearer.
Acked-by: Nicolas Ferre <nicolas.ferre@...el.com>
I plan to queue these patches really soon on top of my
at91-3.20-cleanup branch.
Thanks, bye.
