Yes, and I do that. The problem is many of the embedded boards map
stuff
above 0xff000000 (or 0xf0000000), which overlaps your "standard" PowerPC
in/out mapping.
On systems that have PCI bridges, legacy hardware, and want to use
the standard drivers that in/out, I have to put the IO_BASE someplace
else, or remap everything later when the VM allocator is initialized.
