commit c4c5d40abd4355ce6bbd8c9845f20fe39f6998b3 from https://github.com/altera-opensource/linux-socfpga.git socfpga-6.6.22-lts. Implement DebugFS for the FPGA Manager Framework. Each FPGA gets its own directory such as <debugfs>/fpga_manager/fpga0 and three files: * [RW] flags = flags as defined in fpga-mgr.h * [RW] firmware_name = write/read back name of FPGA image firmware file to program * [WO] image = write-only file for directly writing fpga image w/o firmware layer Enabled by CONFIG_FPGA_MGR_DEBUG_FS Signed-off-by: Alan Tull <atull@opensource.altera.com> Signed-off-by: Liwei Song <liwei.song@windriver.com>
