drm/nouveau/flcn: new code to load+boot simple HS FWs (VPR scrubber)
Adds the start of common interfaces to load and boot the HS binaries provided by NVIDIA that enable the usage of GR.
ACR already handles most of this, but it's very much tied into ACR's init process, and there's other code that could benefit from reusing a lot of this stuff too (ie. VBIOS DEVINIT/PreOS, VPR scrubber).
The VPR scrubber code is fairly independent, and a good first target.
- adds better debug output to fw loading process, to ease bring-up/debug
v2: - whitespace, 0->false

drm/nouveau/falcon: add msgqueue interface
A message queue firmware implements a specific protocol allowing the host to send "commands" to a falcon, and the falcon to reply using "messages". This patch implements the common part of this protocol and defines the interface that the host can use.
Due to the way the firmware is developped internally at NVIDIA (where kernel driver and firmware evolve in lockstep), firmwares taken at different points in time can have frustratingly subtle differences that must be taken into account. This code is architectured to make implementing such differences as easy as possible.

drm/nouveau/core: add falcon library functions
Falcon processors are used in various places of GPU chips. Although there exist different versions of the falcon, and some variants exist, the base set of actions performed on them is the same, which results in lots of duplicated code.
This patch consolidates the current nvkm_falcon structure and extends it with the following features:
* Ability for an engine to obtain and later release a given falcon, * Abstractions for basic operations (IMEM/DMEM access, start, etc) * Abstractions for secure operations if a falcon is secure
Abstractions make it easy to e.g. start a falcon, without having to care about its details. For instance, falcons in secure mode need to be started by writing to a different register.
Right now the abstractions variants only cover secure vs. non-secure falcon, but more will come as e.g. SEC2 support is added.
This is still a WIP as other functions previously done by engine/falcon.c need to be reimplemented. However this first step allows to keep things simple and to discuss basic design.

drm/nouveau: fix bogus GPL-2 license header The bulk SPDX addition made all these files into GPL-2.0 licensed files. However the remainder of the project is MIT-licensed, these files were simply missing the boiler plate and got caught up in the global update. Fixes: 96ac6d4351004 (treewide: Add SPDX license identifier - Kbuild) Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/falcon: add msgqueue interface A message queue firmware implements a specific protocol allowing the host to send "commands" to a falcon, and the falcon to reply using "messages". This patch implements the common part of this protocol and defines the interface that the host can use. Due to the way the firmware is developped internally at NVIDIA (where kernel driver and firmware evolve in lockstep), firmwares taken at different points in time can have frustratingly subtle differences that must be taken into account. This code is architectured to make implementing such differences as easy as possible. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/core: add falcon library functions Falcon processors are used in various places of GPU chips. Although there exist different versions of the falcon, and some variants exist, the base set of actions performed on them is the same, which results in lots of duplicated code. This patch consolidates the current nvkm_falcon structure and extends it with the following features: * Ability for an engine to obtain and later release a given falcon, * Abstractions for basic operations (IMEM/DMEM access, start, etc) * Abstractions for secure operations if a falcon is secure Abstractions make it easy to e.g. start a falcon, without having to care about its details. For instance, falcons in secure mode need to be started by writing to a different register. Right now the abstractions variants only cover secure vs. non-secure falcon, but more will come as e.g. SEC2 support is added. This is still a WIP as other functions previously done by engine/falcon.c need to be reimplemented. However this first step allows to keep things simple and to discuss basic design.
