From 443ab715a40881d6c9ba11b027ba154bac904cb0 Mon Sep 17 00:00:00 2001
From: Oswald Buddenhagen <oswald.buddenhagen@gmx.de>
Date: Sat, 10 May 2014 23:19:08 +0200
Subject: [PATCH] MIPS/AR7: ensure that serial ports are properly set up
without UPF_FIXED_TYPE, the data from the PORT_AR7 uart_config entry is
never copied, resulting in a dead port.
