From 9e70d1378c7f41d1aa9ffc5429d810330c194949 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Fri, 24 Sep 2010 01:06:37 +0200 Subject: fsl_diu_fb: further refactoring of FSL DIU code Move common code to the fsl_diu_fb.c file and remove obsolete code from board files (aria, mpc8610hpcd and pdm360ng). Move fsl_diu_fb.h file to the include directory.
