[PATCH] Add support for Prodrive P3M750 & P3M7448 (P3Mx) boards
This patch adds support for the Prodrive P3M750 (PPC750 & MV64460) and the P3M7448 (MPC7448 & MV64460) PMC modules. Both modules are quite similar and share the same board directory "prodrive/p3mx" and the same config file "p3mx.h". Signed-off-by: Stefan Roese <sr@denx.de>
