Thanks, that is how I had set it up locally,
just direct address and it worked. It was good
to get some second hand confirmation on that.
I am new to NetBSD, so the config can seem
a little opaque at times.

I can't think of any other way to specify this. I've rattled up an=20
evbppc-specific defflag "EVBPPC_BUS_DMA_NEEDS_P2B" which DTRT if=20
specified in the kernel config file. If there are no objections, I'll=20
As I recall, you just need the following definitions for the macros:
#define PHYS_TO_BUS_MEM(t, addr) (addr)
#define BUS_MEM_TO_PHYS(t, addr) (addr)
