FYI, I like this series, but I held off applying it because I wanted to
verify that the shuffling of the memory regions works on the existing
8996 boards.

Unfortunately it didn't work, either with or without the shuffling on
the db820c - and I've not found the time to figure out why that is. I
hope to get back to this shortly (or that someone else will figure it
out and provide a tested-by)

Regards,
Bjorn
