From 38bd6892abbf7d60b1e9ff7f1a2b8019b552eed3 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Tue, 28 May 2013 22:13:52 +0200 Subject: arm: add debug uarts for rockchip rk29xx and rk3xxx series Uarts on all recent Rockchip SoCs are Synopsis DesignWare 8250 types. Only their addresses vary very much. This patch adds the necessary definitions to use any of the uart ports for early debug purposes.
