From c757a50bd12b4f4f1c44a7cc42354918e8d60cd7 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 22 Oct 2014 16:47:47 +0800 Subject: ARM: sunxi: Add support for using R_UART as console The A23 only has UART0 muxed with MMC0. Some of the boards we encountered expose R_UART as a set of pads. Add support for R_UART so we can have a console while using mmc.
