These patches add HuC loading support. The GuC is required to authenticate the HuC. The userspace patches that check for a fully loaded HuC firmware and use it can be found at: https://lists.freedesktop.org/archives/libva/2016-September/004554.html https://lists.freedesktop.org/archives/libva/2016-September/004555.html More information regarding the HuC, batch commands that configure the HuC etc can be found at- https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-skl-vol02a-commandreference-instructions-huc.pdf https://www.x.org/docs/intel/CHV/intel-gfx-prm-osrc-chv-bsw-vol10-hevc.pdf v2: rebased. v3: rebased. Changed the code following the review comments. v4: Added action_lock initialization fix provided by Arek (Hiler Arkadiusz) to the first patch in the series- Make the GuC fw loading helper functions general. v5: rebased on top of drm-tip. The patch series is now in sync with GuC code reorganization efforts by Arek- https://patchwork.freedesktop.org/series/15896/ v6: rebased. Organize the code-move contents of intel_huc.h to intel_uc.h. Update functions intel_huc_load(),intel_huc_init() and intel_uc_fw_fetch() to accept dev_priv instead of dev.
