[POWERPC] Xserve G5 thermal control fixes
The thermal control for the Xserve G5s had a few issues. For one, the way to program the RPM fans speeds into the FCU is different between it and the desktop models, which I didn't figure out until recently, and it was missing a control loop for the slots fan, running it too fast. Both of those problems were causing the machine to be much more noisy than necessary. This patch also changes the fixed value of the slots fan for desktop G5s to 40% instead of 50%. It seems to still have a pretty good airflow that way and is much less noisy. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
