This one has 36bit physical address space. You can verify that via

While the physical address of your ioremap is 47000ee000.

2^ 36 == 1000000000
---->    47000ee000

So the fault is not very surprising. Unfortunately we do not check,
whether physaddr is inside the valid physical address space. I whip up
a patch to do that.

Can you please instrument the driver to figure out where this
information comes from ? Or maybe lspci tells already.

Thanks,
