To initiate the reprogramming itself, adevice reset is required. The SBI SRST extension's "cold reboot" cantrigger such a device reset, provided corresponding support has beenenabled in the HSS (Hart Software Services), the provider of SBI runtimeservices on PolarFire SoC.While this is a driver responsible for the reprogramming of an FPGA,there is no dynamic discovery of devices involved, as runtimereconfiguration is not possible due to the device reset requirements.Therefore FPGA manager subsystem is not used by this driver and the FPGAsubsystem maintainers were unwilling to accept it there.Signed-off-by: Conor Dooley <conor.dooley@microchip.com> List of files: /linux-6.15/drivers/firmware/microchip/Makefile Fri, 20 Oct 2023 13:18:43 +0000 Conor Dooley <conor.dooley@microchip.com>
