I couldn't find an "attach patch" either. I believe it was folded
into gdb. You can specify arguments to the simulator either at the
gdb command prompt or in the .gdbinit file using the target command.
I'm currently using this in my .gdbinit:

target sim -e chirp -r 33554432
set architecture powerpc:604
load

You can specify device tree information on the target line using -o
for individual entries or -f to specify a file with the device tree
to be merged in.
