I can't think of any other way to specify this. I've rattled up an 
evbppc-specific defflag "EVBPPC_BUS_DMA_NEEDS_P2B" which DTRT if 
specified in the kernel config file. If there are no objections, I'll 
commit this.

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)
