This patch series adds support for AM62x ESM (Error Signaling Modules).
The Error Signaling Module (ESM) aggregates events and errors from throughout the device into one location. It can signal interrupts to a processor to deal with an event, and manipulate an error pin to signal an external hardware that an error has occurred. Therefore an external controller is able to reset the device. Two ESM can be used : one for main domain devices and another one for MCU domain devices. Event outputs generated by main ESM can be routed to MCU ESM as inputs, and trigger MCU ESM generating its event outputs.
Following are required in defconfig: CONFIG_ESM_K3=y CONFIG_SPL_MISC=y CONFIG_SPL_DRIVERS_MISC=y
