Hi,

Trying to change PCI IO window base for 52xx target I found that
we are pretty much limited to a "0" offset only.

We just fixed that for 64 bits but 32 bits still has the limitation.
Note that it's not a very good idea to have your IO range at !0 if
you're going to use anything ISA-like, such as a VGA video card or other
legacy devices behind a PCI southbridge or SuperIO.

The chances of that on an MPC52xx platform are practically zero, aren't
they?
