From 61b59e2749451d86e73139a81f9f8995e2f4a932 Mon Sep 17 00:00:00 2001 From: Ajay Kumar Date: Tue, 8 Jan 2013 20:42:25 +0000 Subject: [PATCH] video: Modify exynos_fimd driver to support LCD console Currently, exynos FIMD driver is being used to support only TIZEN LOGOs. In order to get LCD console, we need to enable half word swap feature of FIMD and use 16 BPP. LCD console and proprietary Logo cannot be used simultaneously. We use "logo_on" field inside vidinfo_t structure to decide whether user wants Logo or Console. Define CONFIG_CMD_BMP and make logo_on = 1 to get Logo on screen. Use logo_on = 0 to get output console on LCD.
