From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eric Nelson Date: Tue, 29 Apr 2014 14:13:22 -0700 Subject: [U-Boot] [PATCH] video: mxc_ipuv3_fb: stash frame buffer pointer in global data. Message-ID: <1398806002-25067-1-git-send-email-eric.nelson@boundarydevices.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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.
