So seems there is no big difference on processing 'reconfig' & 'reimage' in FPGA mgr framework. We may not have to introduce 2 sets of ops in fpga_mgr.
Could we just reuse the fpga_mgr_ops for reimage? The fpga_mgr_ops.write_init() will pass the fpga_image_info to device driver, and driver could be aware of the REIMAGE flag. Just like the handling of other flags in fpga_image_info.
Thanks, Yilun
