com.c needs to know about mem mapped ports in ppc systems.

ncr.c and if_de.c needs some hooks for systems with ncr and dec
ether chips on the motherboard that runs on odd clocks and doesn't
support a srom. srom is emulated in machine dependent code.

big endian support for ncr and dec ether finished. the 21040
have some more coding requirements if it is to run BE since
it does not have the descriptor endian swap configuration bit.
