mpc8xx arch support

Hi folks,

I was going to attempt to compile NetBSD/powerpc for mpc8xx to see if I
could just about get it running on an Cyclades AlterPath console server
(just an interesting project). Looking through the powerpc port, I can
see there are references to the relevant machine dependant files but
they do not seem to exist in 8.0 or earlier sources.

i.e. in files.powerpc:

]] # MPC8xx (Power QUICC 1) Family files
]] file	arch/powerpc/mpc8xx/mpc8xx_machdep.c		ppc_mpc8xx
]] file	arch/powerpc/mpc8xx/mpc8xx_cache.c		ppc_mpc8xx
]] file	arch/powerpc/mpc8xx/mpc8xx_pmap.c		ppc_mpc8xx
]] file	arch/powerpc/mpc8xx/mpc8xx_stubs.c		ppc_mpc8xx
]] file	arch/powerpc/mpc8xx/copyin.c			ppc_mpc8xx
]] file	arch/powerpc/mpc8xx/copyout.c			ppc_mpc8xx
]] file	arch/powerpc/mpc8xx/kcopy.c			ppc_mpc8xx
]] file	arch/powerpc/mpc8xx/trap.c			ppc_mpc8xx

Anyone have any ideas if these files *actually* exist?

This is my first time routing around in the netbsd kernel so I am
probably a bit lost.

Thanks,

Aaron
