From a69214dc719862b8433608d7e914e51464dfd14c Mon Sep 17 00:00:00 2001 From: Eric Nelson Date: Tue, 29 Apr 2014 14:37:56 -0700 Subject: video: mxc_ipuv3_fb: stash frame buffer pointer in global data. This patch updates the i.MX video driver to store the frame-buffer address in the fb_base field of the global data structure *gd. By doing this, you can find the frame buffer address using the 'bdinfo' command: U-Boot > bdinfo arch_number = 0x00000EB9 ... FB base = 0x4F35F1C0 This is very useful when debugging display connections.
