Attempting to enable&use watchdog in 8343; but run into Assembler
(v.2.15) problem in cpu/mpc83xx/start.S:424
/* and reset it */
	li	r4, 0x556C
	sth	r4, SWSRR at l(r3)
	li	r4, 0xAA39    <-------- gas barks here, 0xAA39 > 0x8000
	sth	r4, SWSRR at l(r3)

which I do not understand, since I thought 'li' was an UNsigned 16bit
load. I can work around it in a kludgey way with.

	lis	r4, 0
	ori	r4, r4, 0xAA39
	sth	r4, SWSRR at l(r3)

but wonder if one you PowerPC assembler gurus could offer better suggestion.
