From b0895384bebb6a4a2ea5bbdb0941b771b5875012 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 15 Jun 2017 21:37:50 -0600 Subject: [PATCH] Allow displaying the U-Boot banner on a video display At present the U-Boot banner is only displayed on the serial console. If this is not visible to the user, the banner does not show. Some devices have a video display which can usefully display this information. Add a banner which is printed after relocation only on non-serial devices if CONFIG_DISPLAY_BOARDINFO_LATE is defined.
