From 1eb1391638633cdeb7dcaacd295bfcbec216ea8f Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Sat, 24 Dec 2011 00:59:03 +1000 Subject: m68knommu: simplify the 527x UART setup code Simplify the UART setup code so that it no longer loops for each UART present. Just make it do all the work it needs in a single function. This will make the code easier to share when we move to a single set of platform data for ColdFire UARTs.
