[PATCH 0/2] drm/nouveau/bios/init: Improve pre-PMU devinit opcode coverage

NVIDIA GPUs include a common scripting language (devinit) that can be
interpreted by a number of "engines", e.g. within a kernel-mode software
driver, the VGA BIOS or an on-board small microcontroller which provides
certain security assertions (the 'PMU').

This system allows a GPU programming sequence to be shared by multiple
entities that would not otherwise be able to execute common code.

This series adds support to nouveau for two opcodes seen on VBIOSes prior
to the locked-down PMU taking over responsibility for executing devinit

Documentation for these two opcodes can be found at:
