I tested them on U300 which has an unmodified PL011 block, both with
and without DMA support compiled in. I have tested the Pl180 mods
on the U300 as well, it has a slightly modified PL180 block.
I have no other hardware...

I will try too boot it up in the QEMU emulator, it has an emulated
PL011 atleast that should account for something? I don't think
it emulates the PL180 though. :-(

I understand this. I will have to try to dig out some ARM reference
design from somewhere, I cannot afford one sadly.

ARM Ltd. people on this list: if you can send me a versatile
machine, mail me in private for post address...
