This is a simplied version of the fix by Roy in fdo#93629. While this
doesn't appear to fix the issues for the users in that report, it's a
real issue that deserves to be resolved.

Also removes an XXX; according to nvgpu headers the field is called
NV_PGRAPH_GPCS_SWDX_TC_BETA_CB_SIZE_DIV3, so, apparently not some
magic we need to figure out :)

This was really inconsistent, some implementations could touch PPCs
that didn't exist, others neglected to touch ones that did.

Add secure boot support for the GM20B chip found in Tegra X1. Secure
boot on Tegra works slightly differently from desktop, notably in the
way the WPR region is set up.
In addition, the firmware bootloaders use a slightly different header
format.

Add secure-boot for the dGPU set of GM20X chips, using the PMU as the

This work is based on Deepak Goyal's initial port of Secure Boot to
Nouveau.

The firmwares required by GR may vary from chip to chip, especially with
the introduction of secure boot and NVIDIA-provided firmwares. Move the
firmware loading outside of gf100_gr_ctor so other chips may still call
it while managing their firmwares themselves.

Some members of gf100_gr were freed by the gk20a driver. That's not
where it should be done - free them in gf100 so other chips that use
NVIDIA-provided firmware free these structures properly.
This also removes the need for a GK20A-specific destructor.

Most of the per-chipset differences will go away when we fully switch
to using the register lists provided by the firmware files, which will
leave all the remaining code "belonging" to GM200.
This is a preemptive rename from GM204 to GM200.

Each GPCCS unit was reading the mask from GPC0, which causes problems on
boards where some GPCs are missing PPCs.
Part of the fix for fdo#92761.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
There's a few places where we need to access a GPC register from ucode,
but outside of the falcon's io address space. To do this we need to
calculate the offset based on which GPC we're executing on.
This used to be done manually, but we've since found a "base" offset
that can be added by the hardware. To use this, an extra bit needs to
be set in the register address, which is what this macro achieves.
There should be no functional change from this commit.
