| |
This patch adds preliminary support for the IBM PowerPC 750GX. In summary this part is a PPC750FX ramped to 1 GHz with a 1MB 4-way L2 and more advanced I/O pipelining. It is beginning to appear in embedded systems and was rumored to be under evaluation inside Apple. Tested on PVR 70020101; please merge.
