[PATCH 2/3] (Resend part #1) Add the RapidIO support to powerpc architecture with memory mapping support.

Zhang Wei wei.zhang at FREESCALE.COM
Fri Dec 21 20:58:43 EST 2007


The patch adds the RapidIO support to powerpc with of-device support.
New Serial RapidIO of new Freescale processor, such as MPC8548, MPC8568,
is also added.
