freebsd-dev/sys/powerpc/psim/psim-tree
Peter Grehan 174e81ed65 - 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 :-)

# The .gdbinit should contain something like:
#
# target sim -e chirp -r 33554432 -f psim-tree
# load
#
# (The -r option is the amount of physical RAM the simulator has)
