From 8ec64a0a881cb7b6ff8c3f73157f82ef384f1f34 Mon Sep 17 00:00:00 2001
From: Hawking Zhang <Hawking.Zhang@amd.com>
Date: Wed, 10 Jan 2018 18:12:44 +0800
Subject: [PATCH 2160/2940] drm/amdgpu/gfx10: new approach to load pfp fw (v4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
gfx10 allows to only upload pfp jumptable while save the whole
pfp image at gtt memory.
v2: program CP_PFP_IC_BASE_CNTL to default value
v3: switch to use amdgpu_bo_create_reserved to create pfp fw bo
v4: split common code from gfx10 code
