Subject: drm/nouveau/bios: split out shadow methods

We're about to need to be able to fetch additional chunks of data beyond
the primary bios image, which makes fetching a lot more complicated.

This splits out the verious shadowing routines to be nothing more than
very dumb "fetch this much data from this offset" routines, and leaves
the logic of what and how much to fetch in common code.

From ba6e34e612718b81744dfb1acb408cfb0043d6e4 Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Tue, 23 Sep 2014 15:42:45 +1000
Subject: drm/gm204/devinit: initial implementation

Starting from GM204, certain registers are no longer accessible by the host
(or unsigned PMU firmware).

This commit implements devinit on PMU, using a signed microcode image, and
devinit data, from the VBIOS.

Subject: drm/nouveau/bios: log if auxch accesses fail, also return 0x00 from
 rd when it does

Logging at trace level, rather than as en error, as it seems conceivable
that failure could be normal under certain circumstances (new bios,
older sink that doesn't support a particular DPCD address)

Subject: drm/gf110-/disp: magic that might help some tmds issues

The binary driver has been doing this since GF119, and we've somehow
gotten away with it.  But, TMDS that hasn't been initialised already
by the x86 vbios code is distorted without it on GM204.

From c21e6b302a1eac4b3379bf8e472fffb8dda18371 Mon Sep 17 00:00:00 2001

Subject: drm/gm204/disp: some magic that fixes bringup of uninitialised
 outputs

Probably missing something here, doesn't make a lot of sense to write
or+link data into a register whose offset is calculated by the same
or+link info..

This is the all I've witnessed the binary driver and vbios doing so
far, so it'll do.

Subject: drm/nouveau: introduce nv_device_is_cpu_coherent()

Add a function allowing us to know whether a device is CPU-coherent,
i.e. accesses performed by the CPU on GPU-mapped buffers will
be immediately visible on the GPU side and vice-versa.

For now, a device is considered to be coherent if it uses the PCI bus on
a non-ARM architecture.

Subject: drm/gk20a/clk: fix max VCO value

For some reason max_vco was set to a lower value that it can support,
which prevented some clock states to be applied. Fix this by setting it
to the same value as downstream.

Subject: drm/nouveau/bios: add parsing of BIT M(v2) +0x03 table

We only support one kind of matching here (ramcfg strap), but it appears
alternate methods are possible.  I wrote a tool to scan our vbios repo
for other types, but did not see any used.  Hopefully this means there
aren't any in the wild that will now break.

Subject: drm/nouveau/bios: translate ramcfg strap through M0203

A machine has been spotted where the ramcfg strap is "8", and the ramcfg
xlat table goes 0-7,0-7, resulting in us selecting config 0 for memory
items.  On this particular system, config "8" is available and supposed
to be used.  It appears that starting from GT21x (where Mv2 appears),
we're supposed to use the value in this table instead.

One concern here is that not all the places we currently use ramcfg xlat
are supposed to be treated the same now.  The strap xlat table wasn't
removed from the vbios either, presumably for some kind of good reason.
