From e9934f0b6032d5f4304fa17241c870b95e7e60f8 Mon Sep 17 00:00:00 2001 From: Stefano Babic Date: Wed, 28 Sep 2011 11:21:15 +0200 Subject: VIDEO: MX5: Switch MX5 to CONFIG_VIDEO The framebuffer driver for MX5 is based on CONFIG_LCD. In the current implementation, there is a serious bug because the required memory is allocated before relocation, but the driver knows only later which is the resolution of the display. The patch switches the driver to CONFIG_VIDEO and the memory is allocated by the driver itself. We also need to switch the vision2 board code and config file in the same commit so that this commit will be bisectable.
