core: add support for secure boot
On GM20x and later GPUs, firmware for some essential falcons (notably
FECS) must be authenticated by a NVIDIA-produced signature and loaded
by a high-secure falcon in order to access certain registers, in a
process known as Secure Boot.
Secure Boot requires the building of 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 a priviledged mode.
This patch adds infrastructure code to support this process on chips
that require it.
