Thomas, can't you use ioreadxx() and friends instead of rolling your own
memory mapped I/O handlers?
well, at least ioread32be/iowrite32be are looking promising, but a quick
grep didn't show them for m68k.
Someone could submit a patch ...
readxx() and friends are only to be used on PCI-like buses.
hmm, afaik readxx/writexx is not directly related to PCI. It's
like ioread/iowrite to access iomapped address space. The difference
to ioread/iowrite is that it doesn't support PCI IO space.
That's correct ... at least that's the meaning we've ascribed on other
architectures I've worked on. Any ioremap'd memory area can be accessed
by readX/writeX. The current list of Buses I know it works on is MCA,
EISA, GSC, Runway ... in addition to PCI.
