[PATCH v3] [POWERPC] 85xx: Add basic Uniprocessor MPC8572 DS port

Kumar Gala galak at kernel.crashing.org
Wed Sep 12 05:37:56 EST 2007


Added basic board port for MPC8572 DS reference platform that is
similiar to the MPC8544/33 DS reference platform in uniprocessor mode.

---

Rev 3 -- updates to the device tree based on discussion on how we want
to handle memory busses going forward.
