drm/vmwgfx: Rework screen target page flips v2
Gnome-Shell / Wayland assumes that page-flips can be done on a crtc
regardless of framebuffer size and the crtc position within the
framebuffer.
Therefore rework the screen target code to correctly handle changes in
framebuffer size and content_fb_type. Also make sure that we update
the screen target correctly when the content_fb_type is not
SAME_AS_DISPLAY.
This commit breaks out the framebuffer binding code from crtc_set so it
can be used both from page_flip() and crtc_set() and reworks those
functions a bit to be more robust.

drm/nouveau/core: add support for secure boot
On GM200 and later GPUs, firmware for some essential falcons (notably
GR ones) must be authenticated by a NVIDIA-produced signature and
loaded by a high-secure falcon in order to be able to access privileged
registers, in a process known as Secure Boot.
Secure Boot requires building a binary blob containing the firmwares
and signatures of the falcons to be loaded. This blob is then given to
a high-secure falcon running a signed loader firmware that copies the
blob into a write-protected region, checks that the signatures are
valid, and finally loads the verified firmware into the managed falcons
and switches them to privileged mode.
This patch adds infrastructure code to support this process on chips
that require it.
v2:
- The IRQ mask of the PMU falcon was left - replace it with the proper
irq_mask variable.
- The falcon reset procedure expecting a falcon in an initialized state,
which was accidentally provided by the PMU subdev. Make sure that
secboot can manage the falcon on its own.
