Due to the GPU preventing us from touching NV_PLTCG_LTCS_LTSS_CBC_BASE,
we cannot provide CBC/ZBC support without signed PMU firmware to handle
the task for us...

GP100 still supports the previous generations' page table layout, which
we will temporarily make use of here.
Proper support for the new MMU layout requires some rework to the common
MMU code, which is in progress.

GFxxx/GM1xx support the selection of 64/128KiB big pages globally.
GM2xx supports the same, as well as another mode where the page size
can be selected per-instance.
We default to 128KiB pages (With per-instance for GM200, but the current
code selects 128KiB there already) as the MMU code isn't currently able
to handle otherwise.

Makes common the code that was previously used by the PMU table parsing,
as it appears other tables need this too.
Not much of an idea what this is all about...

Some VBIOS have separate tables for each link of a given output path,
which means we have to specify the specific link we're using instead
of all possible links.

Corresponds with GT215. Don't rely on the lock test logic being
unconditionally enabled, and disable test logic when done (presumably
to save power).

Defer the loading of firmware files to the chip-specific part of secure
boot. This allows implementations to retry loading firmware if the first
attempt failed ; for the GM200 implementation, this happens when trying
to reset a falcon, typically in reaction to GR init.
Firmware loading may fail for a variety of reasons, such as the
filesystem where they reside not being ready at init time. This new
behavior allows GR to be initialized the next time we try to use it if
the firmware has become available.

Make it possible to call gm20x_secboot_prepare_blobs() several times
after either success or failure without re-building already existing
blobs. The function will now try to load firmware files that have
previously failed before returning success.

Handle and propagate secure boot errors. Failure to do so results in
Nouveau incorrectly believing init has succeeded and a completely
black display during boot. If we propagate the error, GR init will fail
and the user will at least have a working display.

This patch adds support for advanced features supported by the
Noise-Aware PLL of Maxwell. Glitchless switch allows the PL field to be
updated without disabling the PLL first if the SYNC_MODE bit of the CFG
register is set.
More significantly, DFS allows the PLL to monitor the actual input
voltage and to dynamically lower the output frequency accordingly. This
allows the clock to be more tolerant of lower voltages.
These improvements are only supported for Tegra speedos >= 1.
Also add the voltage table that is suitable for GM20B's NAPLL. This
change needs to be done atomically for the right voltages to be used by
the clock driver.
v2. Fix build on non-Tegra platforms

Split the MNP programming function into two functions for the cases
where we allow sliding or not, instead of making it take a parameter for
this. This results in less conditionals in the code and makes it easier
to read.
Also make the MNP programming functions take the PLL parameters as
arguments, and move bits of code to more relevant places (previous
programming tended to be just-in-time, which added more conditionnals in
the code).
