ads fads 860 patch

Hello all,

Here comes my embedded-2.2.13 patch for ADS and FADS.

The following works:

ADS and FADS NFSROOT.
Only 860 tested.

Does not work:

fec.c with FADS860T.

The following files are not properly changed
they are only changed to be able to compile.... quick fix.

arch/ppc/kernel/ksysm.c
arch/ppc/kernel/setup.c
arch/ppc/mm/init.c

They have nothing to do with ADS / FADS.

Have a nice weekend!

Cheers /

Magnus Damm
