1. An Information Handling System (IHS), comprising:
a heterogeneous computing platform having a Reduced Instruction Set Computer (RISC) processor and a plurality of devices coupled to an interconnect; and
an external embedded controller (EC) coupled to the interconnect via a bridge integrated into the heterogeneous computing platform, wherein the bridge is configured to provide the external EC with access to the plurality of devices, at least in part, using a virtualized General Purpose Input/Output (GPIO) pin or wire, wherein the RISC processor and the plurality of devices are coupled to a run voltage rail, wherein the external EC is coupled to an always-on voltage rail, and wherein the external EC is configured to run the plurality of devices autonomously or independently of the operation of the RISC processor.
