b448a266cc drm/nouveau/nvfw: firmware structures should begin with nvfw_
Rename all structures that are used directly by firmware to have a nvfw_
prefix.

This makes it easier to identify structures that have a fixed, specific
layout.  A future patch will define several more such structures, so it's
important to be consistent now.

d114a1393f drm/nouveau/flcn/msgq: move handling of init message to subdevs
When the PMU/SEC2 LS FWs have booted, they'll send a message to the host
with various information, including the configuration of message/command
queues that are available.

Move the handling for this to the relevant subdevs.

e9602a1bd7 drm/nouveau/flcn/msgq: simplify msg_queue_pop() error handling
We always want at least requested size, make anything less a more direct
error condition.

8e90a98dfb drm/nouveau/flcn/qmgr: support syncronous command submission from common code
Functions implementing FW commands had to implement this themselves, let's
move that to common code and plumb the return code from callbacks through.

c80157a25e drm/nouveau/flcn/qmgr: allow arbtrary priv + return code for callbacks
Code to interface with LS firmwares is being moved to the subdevs where it
belongs, rather than living in the common falcon code.

Arbitrary private data passed to callbacks is to allow for something other
than struct nvkm_msgqueue to be passed into the callback (like the pointer
to the subdev itself, for example), and the return code will be used where
we'd like to detect failure from synchronous messages.

22431189d6 drm/nouveau/flcn/msgq: explicitly create message queue from subdevs
Code to interface with LS firmwares is being moved to the subdevs where it
belongs, rather than living in the common falcon code.

This is an incremental step towards that goal.

7e1659cc3b drm/nouveau/flcn: split msgqueue into multiple pieces
To make things clearer while modifying the interfaces, split msgqueue into
Queue Manager, Command Queue, and Message Queue.

There should be no code changes here, these will be done incrementally.
