From b264c3527930ca4812fefc505fde9ad99d8a0117 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 21 Jun 2005 17:15:21 -0700 Subject: [PATCH] [PATCH] ppc32: Converted MPC10X bridge to use platform devices instead of OCP Converted the MPC10x bridge support (used by MPC10x and 8240/1/5) to used the standard platform device model.
