From 6dde5ac5220b3b9c28f82f291b64eca3e5ebe80d Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Sun, 16 Sep 2012 20:50:45 +0800 Subject: [PATCH] ARM: imx: move debug macros to include/debug Move imx debug-macro.S over to common debug macro directory. It removes the inclusion to hardware.h by hard-coding the physical address of uart port and copying IMX_IO_P2V from hardware.h. Since we will need a common solution, which might use a fixed virtual address for uart port across platforms, we make a copy of IMX_IO_P2V here as a temporary solution to enable low-level debug for imx multi-platform build.
