From 0740ec0893ea1d74a217000d684e79b6e648bb9d Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 23 Jun 2021 12:32:42 -0500 Subject: [PATCH] remoteproc: pru: Add support for various PRU cores on K3 AM64x SoCs The K3 AM64x family of SoCs have a ICSSG IP that is similar to the version on AM65x SR2.0 SoCs with some minor differences. 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.
