From ec5b0f1193ad461e53d083edad8fab0298fe68e3 Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Fri, 20 Oct 2023 14:18:43 +0100 Subject: firmware: microchip: add PolarFire SoC Auto Update support Add support for Auto Update reprogramming of the FPGA fabric on PolarFire SoC, using the fw_upload mechanism a la the intel-m10-bmc-sec-update driver. This driver only writes the image to the spi flash & performs validation on it, as the entire FPGA becomes unusable during the actual reprogramming of a bitstream. To initiate the reprogramming itself, a device reset is required. The SBI SRST extension's "cold reboot" can trigger such a device reset, provided corresponding support has been enabled in the HSS (Hart Software Services), the provider of SBI runtime services on PolarFire SoC. While this is a driver responsible for the reprogramming of an FPGA, there is no dynamic discovery of devices involved, as runtime reconfiguration is not possible due to the device reset requirements. Therefore FPGA manager subsystem is not used by this driver and the FPGA subsystem maintainers were unwilling to accept it there.
