The Intel Remote System Update (RSU) provides a way for users to update the QSPI configuration bitstream of a Intel Stratix 10 SoC device with significantly reduced risk of corrupting the bitstream storage and bricking the system.
This patch provides console commands to exercises the RSU APIs at Intel Stratix10 SoC. The commands use the term "slot" to refer to a sub-partition which is intended to contain a production image, and the term "priority" to refer to the fact that the images are loaded by firmware in the defined order.
The provided console commands are below, you can also refer to the header file rsu.h for the details of RSU APIs: slot_count slot_by_name slot_get_info slot_size slot_priority slot_erase slot_program_buf slot_program_buf_raw slot_verify_buf slot_verify_buf_raw slot_enable slot_disable slot_load slot_load_factory slot_rename status_log list dtb update notify clear_error_status reset_retry_counter
