Subject: RE: [PATCH 00/11] ARM: PrimeCell DMA Interface v5

The latest patchset is now also tested on the ARM-RealView
PB11MPCore. My best friends over at Ericsson AB helped me
out by lending me their board for a short session.

See bootlog below...

- UART console comes up fine and is interactive
- MMCI card mounts and you can list and copy files

No DMA in use since the PL081 in this machine does not
have a driver yet, but no regressions in sight.

This should be similar to Versatile or Integrator.

Is this OK now Russell?

Yours,
Linus Walleij
