Please address the comments I had in v3 of this patch:
https://patchwork.ozlabs.org/patch/1261047/

If you just send a new version of the patch that won't convince me to take it.
We will need to make sure that we are fine with patch. Especially I'm concerned
about the limitation of the device to only be able to access the first GiB of
RAM for DMA. I'd like to see an explanation why this won't happen on U-Boot.

Regards,
Matthias
