I'm fine with that. The arm920t/at91 boards do build (with minor
warnings in at91_emac and at91rm9200_usart) and work on real hardware
since 9e8df9c4db7835152996c96cc432dc6dd70bb17c

The warnings are:
 - 'at91_emac.c:487:2: warning: dereferencing type-punned pointer will
    break strict-aliasing rules' in at91_emac -> you know about that
   ... it is the same as in macb driver and will also be fixed soon.
 - 'at91rm9200_usart.c:39:2: warning: #warning Please update to use C
    structur SoC access !' -> at91rm9200_usart will be removed soon

Therefore I do not see any reason to remove those arm920t/at91 boards.

I will do some more testing with atmel_usart driver on atrm9200 devices
and send for review this weekend. The big removal of old-style
at91rm9200 boards can begin after that cause the deprecated
at91rm9200_usart driver needs some outdated stuff which will also be
removed in that step.

Besides that, I found out cpu.c (in that commit) is missing a GPL header
and copyright notice. So please do not add this version.

regards

Andreas Bießmann
