The ICSSG IP on K3 AM64x SoCs have the same set of two PRU cores, two RTU cores and two auxiliary PRU cores called Transmit PRUs (Tx_PRUs).

The AM64x SoCs contain two instances of this newer ICSSG IP. Each ICSSG processor subsystem contains 2 primary PRU cores, 2 auxiliary PRU cores called RTUs, and 2 new auxiliary cores called Transmit PRUs (Tx_PRUs). Enhance the existing PRU remoteproc driver to support all these PRU, RTU and Tx_PRU cores by using specific compatibles. The cores have the same memory copying limitations as on AM65x, so reuses the custom memcpy function within the driver's ELF loader implementation. The initial names for the firmware images for each PRU core are retrieved from DT nodes, and can be adjusted through sysfs if required.
