The AM64x SoC uses a central Device Management and Security Controller (DMSC) processor that manages all the low-level device controls including the system-wide SoC reset. The system-wide reset is managed through the system reset driver.
Add a sysreset controller node as a child of the dmsc node to enable the "reset" command from U-Boot prompt for the K3 AM642 SK.
