Patch 1 adds the binding for the NVIDIA GB200-UT3.0b platform. Patch 2 adds the device tree for the NVIDIA GB200-UT3.0b platform. This is an Aspeed AST2600 based unit testing platform for GB200. UT3.0b is different than nvidia-gb200nvl-bmc due to networking topology differences, additional gpio expanders, and voltage regulator gating some devices. Reference to Ast2600 SOC [1]. Reference to Blackwell GB200NVL Platform [2].
