Hi Alan

Thanks for the comments, I will fix this in the next version.

  * @sgt: scatter/gather table containing FPGA image
  * @buf: contiguous buffer containing FPGA image
  * @count: size of buf
+ * @region_id: id of target region
  * @overlay: Device Tree overlay
  */
 struct fpga_image_info {

Thanks
Hao
