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).
