I have tested this patch on the following boards / tool chains:


Tool Chain:	ELDK 3.1.1	ELDK 4.0	ELDK 4.2
		gcc-3.3.3	gcc-4.0.0	gcc-4.2.2
Board:		binutils-2.14	binutils-2.16.1	binutils-2.17.50.0
TQM834x		OK		OK		OK
Canyonlands	NOK1		OK		OK
MPC5121ADS	OK		OK		OK
Haleakala	OK		OK		OK
Ocotea		NOK1		OK		OK

NOK1: build error because old compiler does not accept "-m440" option


So I would say this looks pretty good :-)

Best regards,

Wolfgang Denk

That said, there may be good reasons for what you did beyond obsequi-
ous sycophantic parody. Perhaps you might be so kind as to elucidate.
