From 447c6cb5674ef0908dbb1297054688b90b909693 Mon Sep 17 00:00:00 2001

Subject: - add a description of what .gdbinit should contain. - add an option
 for the output device in the hope that this can   be made non-blocking at
 some stage. - define an alias for the disk device, required by
 dev/ofw/ofw_disk.c - shift iobus to 0x9000000 so as not to clash with the
 OpenFirmware   entry point of 0x8000400 when address decoding. - down-tone
 comments about the disk dev config :-)
