From 1b504bbe7a4a6c251cdc9dcba1fab72234827945 Mon Sep 17 00:00:00 2001 From: Colin Tuckley Date: Sat, 30 May 2009 13:56:12 +0100 Subject: [PATCH] RealView: Add support for the RealView/PBX platform This is a RealView platform supporting core tiles with ARM11MPCore, Cortex-A8 or Cortex-A9 (multicore) processors. It has support for MMC, CompactFlash, PCI-E.
