Sure, thanks for your suggestion, will update it like this.

* /sys/class/fpga/<fpga.x>/<intel-fpga-fme.x>/bitstream_id
Read-only. Blue Bitstream (static FPGA region) identifier number

* /sys/class/fpga/<fpga.x>/<intel-fpga-fme.x>/bitstream_metadata
Read-only. Blue Bitstream (static FPGA region) meta data

Will update this patch as below.

+Description: Read-only. It returns Blue Bitstream (static FPGA region)
+ identifier number.
