From 5bf9c0b614542d69fb9a8681a0411715cc3e8ba8 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Tue, 3 Mar 2015 15:04:24 -0500 Subject: [PATCH] drm/msm: split out vram initialization We'll want to extend this a bit to handle also a reserved-memory ("stolen") region, so that drm/msm can take-over bootloader splash screen. First split it out into it's own fxn to reduce noise in the following patch.
