From cf64c233839e97221d63ed7887b59196c8c748c3 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Fri, 1 Feb 2008 17:34:08 +1000 Subject: [PATCH] m68knommu: platform setup for 5206e ColdFire parts Switch to platform style configuration for 5206e ColdFire parts. Initial support is for the UARTs. DMA support is moved to common code.
