I've had a "look" into it. This means I rewrote it in some parts to
get it running.

First I tried to do it in nice little steps, so the git commits are
clean and simple. But with my knowldege about the SCLPC, the code your
old SCLPC test driver and my 2.4.25 FPGA driver using SCLPS and
BestComm, one of the commits just got a big rewrite including fixes
for quite some bugs.

The driver is now running using DMA TX and RX. Without BestComm it's
running partly. I'm really windering if this code ever ran before?
There are some historical or future items in there like measurement of
the times, a list_header maybe for future request queueing, and so on.

If you or Ben are interested in my work I can post the patches
here. Of course just to get some comments, because the driver can't be
ready in the state it is. The commits would go on top of Ben's next
