From 5b802344357338a4d645beac8ca97470bcbe3542 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Thu, 4 May 2006 14:07:42 +0100 Subject: [ARM] 3490/1: i.MX: move uart resources to board files Patch from Sascha Hauer This patch moves the i.MX uart resources and the gpio pin setup to the board files. This allows the boards to decide how many internal uarts are connected to the outside world and whether they use rts/cts or not.
