* [PATCH 8/8] drm/i915/get_params: Add HuC status to getparams

  To: intel-gfx; +Cc: Peter Antoine

This patch will allow for getparams to return the status of the HuC.
As the HuC has to be validated by the GuC this patch uses the validated
status to show when the HuC is loaded and ready for use. You cannot use
the loaded status as with the GuC as the HuC is verified after it is
loaded and is not usable until it is verified.

v2: removed the forewakes as the registers are already force-woken.
     (T.Ursulin)
v3: rebased on top of drm-tip. Removed any reference to intel_huc.h
v4: rebased. Rename I915_PARAM_HAS_HUC to I915_PARAM_HUC_STATUS.
Remove intel_is_huc_valid() since it is used only in one place.
Put the case of I915_PARAM_HAS_HUC() in the right place.
v5: rebased. Add a comment to specify that I915_READ(reg)
does not read garbage value. The register HUC_STATUS2 is force
woken and no rpm is needed.

The patches add HuC loading support. The driver builds a frame level
workload which is stored in the graphics memory. This workload is presented
to HuC for processing. The driver, therefore should first determine if the
HuC is enabled and also read the huC athentication status bit to determine
if HuC was successfully loaded. 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://www.x.org/docs/intel/CHV/intel-gfx-prm-osrc-chv-bsw-vol10-hevc.pdf

v2: rebased. Changed the code following the review comments.
v3: rebased. Organize code. Move contents of intel_huc.h to intel_uc.h.
Update function intel_huc_load(),intel_huc_init() and intel_uc_fw_fetch()
to accept dev_priv instead of dev.
v4: rebased. Remove intel_is_huc_valid() since it is called onoly once.
Refactor the code to reduce redundency. Remove fiels like uc_dev which
are no longer used.
v5: rebased. Beautify the code- remove comments that no longer hold
good, add newlines etc.
v6: rebased. Remove further redundency. Correct comments. Replace wait_for
with intel_wait_for_register() for optimisation purpose.Make fw_type an enum.
v7: rebased. Rename intel_huc_loader() to intel_huc(). Move intel_guc_auth_huc()
from intel_uc.c to intel_huc.c. Add return values to DRM_ERRORs.
v8: Use DRM_INFO instead of DRM_ERROR in places that are non-erraneous.
Remove invalidates that are no longer required.

* [PATCH 0/8] HuC Loading Patches

These patches add HuC loading support. The driver builds a frame level
workload which is stored in the graphics memory. This workload is presented
to HuC for processing. The driver, therefore should first determine if the
HuC is enabled and also read the huC athentication status bit to determine
if HuC was successfully loaded. 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://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 code. Move contents of intel_huc.h to intel_uc.h.
Update function intel_huc_load(),intel_huc_init() and intel_uc_fw_fetch()
to accept dev_priv instead of dev.
v7: rebased. Remove intel_is_huc_valid() since it is called onoly once.
Refactor the code to reduce redundency. Remove fiels like uc_dev which
are no longer used.

v2: rebased.
v3: rebased. Changed the code following the review comments.
Changed mainly include renaming certain functions, correcting comments
and changing the yesr in the copyright message. Removed one patch 
from original series: Add guC status to getparams.
v4: Added the file construction method which the HuC follows. This is on similar 
lines to that of GuC. Rewrote the BXT HuC loading patch and wrote a new 
patch for HuC loading on KBL.

  To: intel-gfx; +Cc: Alex Dai, Peter Antoine

From: Peter Antoine <peter.antoine@intel.com>

Rename some of the GuC fw loading code to make them more general. We
will utilise them for HuC loading as well.
     s/intel_guc_fw/intel_uc_fw/g
     s/GUC_FIRMWARE/UC_FIRMWARE/g

Struct intel_guc_fw is renamed to intel_uc_fw. Prefix of tts members,
such as 'guc' or 'guc_fw' either is renamed to 'uc' or removed for
same purpose.

v2: rebased on top of nightly.
    reapplied the search/replace as upstream code as changed.
v3: rebased again on drm-nightly.
v4: removed G from messages in shared fw fetch function.
v5: rebased.
v7: rebased.
v8: rebased.
v9: rebased.
v10: rebased.
