Re: Netra X1 boot getting closer

Some of this is right but key things are wrong.  The PCI DMA usage in
this driver is fundamentally fsck'd up, and it needs fixing.

The changes approach what needs to be done... but you need to adjust the
skip area in a portable manner, and do other changes to PCI DMA.
