This series builds on top of Alex's series[1] to continue initialising the GSP into a state where it becomes active and it starts communicating with the host.
It includes patches to initialise several important data structures required to boot the GSP. The biggest change is the implementation of the command/message circular queue used to establish communication between GSP and host. This is required to configure and boot the GSP. However this series does not get the GSP to a fully active state. Instead it gets it to a state where the GSP sends a message to the host with a sequence of instructions which need running to get to the active state. A subsequent series will implement processing of this message and allow the GSP to get to the fully active state. A full tree including the prerequisites for this patch series is available at https://github.com/apopple-nvidia/linux/tree/nova-core-for-upstream.
