[PATCH] powerpc: Experimental support for new G5 Macs (#2)
This adds some very basic support for the new machines, including the Quad G5 (tested), and other new dual core based machines and iMac G5 iSight (untested). This is still experimental ! There is no thermal control yet, there is no proper handing of MSIs, etc.. but it boots, I have all 4 cores up on my machine. Compared to the previous version of this patch, this one adds DART IOMMU support for the U4 chipset and thus should work fine on setups with more than 2Gb of RAM.
