Well, given my very verbose thread start, including oscillographs, it it not my
intention to leave everyone in the blind.

My 'fix' as it is now, doesn't fix any real problem. It's not finished yet. As it looks
now, it makes the JTAG connection unreliable. Data is getting corrupted when it's
read or written. However, the system no longer hangs up itself.

I will post a patch when I've found a working solution. It's in my best interest
to have it tested and reviewed by you guys, as you understand the clock tree
of this SoC a lot better than I. Besides that, I'd like to have it in the mainline as
well, so we don't have to maintain our patches.
