ARM: dts: aspeed: Add NVIDIA MSX4 HPM

Browse source

The NVIDIA MSX4 HPM (host platform module) is a reference board for
managing up to 8 PCIe connected NVIDIA GPUs via ConnectX-8 (CX8)
SuperNICs. The BMC manages all GPUs and CX8s for both telemetry and
firmware update via MCTP over USB. The host CPUs are dual socket Intel
Granite Rapids processors.
