From 2089b7be2b50078ef27a26fe627173535d13e5ee Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Fri, 8 May 2015 18:28:38 -0700 Subject: [PATCH] imx: ventana: use common uart and i2c setup functions in SPL Now that uart and i2c setup functions have been moved to common.c we can use these and remove code duplication.
