From 84074e5b10acc7154d5aff8630f9379870e71be6 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Thu, 16 Feb 2017 18:57:03 +0900 Subject: [PATCH] drm/nouveau/secboot: put HS code loading code into own file We will also need to load HS blobs outside of acr_r352 (for instance, to run the NVDEC VPR scrubber), so make this code reusable.
