Revision 1263cc67c09bc7f913a6877f3ba0427f0b76617e authored by Benjamin Herrenschmidt on 23 May 2005, 00:03:52 UTC, committed by Linus Torvalds on 23 May 2005, 00:34:42 UTC 
[PATCH] ppc64: Fix booting on latest G5 models
 
The latest speedbumped Apple G5 models have a "bug" in the Open Firmware
device tree that lacks the proper interrupt routing information for the
northbridge i2c controller.  Apple's driver silently falls back into a
sub-optimal "polled" mode (heh, maybe they didn't even notice the bug
because of that :), our driver didn't properly check and crashes :(

This patch fixes our driver to not crash, and adds code to the
prom_init() OF trampoline code that detects the "bug" and adds the
missing information back for this chipset revision.  This fixes booting
and thermal control on these models.
