Subject: [PATCH 00/17] nova-core: Complete GSP boot and begin RPC communication

This series builds on top of Alistair's series [1] to complete the GSP boot
process and get us to a point of making the GSP actual responding with useful
command responses (GspStaticInfo command successfully gets us useful
information about the GPU). The main addition is the sequencer required
to boot pre-Hopper Nvidia GPUs (tested on Ampere GA102).

A full tree including the prerequisites for this patch series is available at the tag:
https://git.kernel.org/pub/scm/linux/kernel/git/jfern/linux.git/tag/?h=nova/upstream-submit-8.29.2025-v5

Alex's series Alistair based [1] off of is at [2].
