From 7bdebba492d92837e7f93e9a6ddfb11a498619b7 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Sat, 24 Dec 2011 01:02:43 +1000 Subject: m68knommu: simplify the 5307 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.
