Are you referring to the IBM PowerPC 405 embedded processor? IBM part numbers are PPC405 (not Motorola MPC505). I am pretty sure that the 4xx numbers are IBM parts. I have seen patches from MontaVista for 405 support in the toolchain, so they may be working with PPC405 chips. David ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
