NICE!

I will add your Tested-by on the patch and send it for Adrian and Ulf
to consider.

You can see that the biffer requests is now even a bit faster than in
the past. This is likely because now we have a bounce buffer of
256K instead of 64K which was what the old bounce buffer code
capped it to.

This exercises the SDMA (it should even be able to use a 512 KB
buffer) better so unless people are very
memory constrained I suggest we keep this.

Yours,
Linus Walleij
