Hi
Please, find the attached patch which enables
powering off the DBAU1200 board.
As a follow up to this one, here's the patch which does the same thing for
DBAu1550 by just reusing Pb1550 code. I added #else because #if renders the
rest of the au1000_halt() code unreachable on DBAu1550/PB1550 anyway.
BR,
Matej
