This is a MPC8555 based board:

	CPU:   8555E, Version: 1.1, (0x80790011)
	Core:  Unknown, Version: 2.0, (0x80200020)

THe do_reset() code is supposed to be the one from
"arch/powerpc/cpu/mpc85xx/cpu.c"

Side note: rebooting Linux doesn't work either - it just hangs the
board in Linux v3.0 and any earlier version I can still compile with
my Fedora15 based host, i.e. down to around 2.6.32 or so.

Will do as PM.

Thanks.
