From 861a86f46047c22af505d7fb27b2c68df0f54323 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 13 Aug 2012 11:37:56 -0700 Subject: [PATCH] omap-common: SPL: Add CONFIG_SPL_DISPLAY_PRINT / spl_display_print() Only omap4/5 currently have a meaningful set of display text and overo had been adding a function to display nothing. Change how this works to be opt-in and only turned on for omap4/5 now.
