+Description:   Read fpga manager status as a string.
+               If FPGA programming operation fails, it could be caused by crc
+               error or incompatible bitstream image. The intent of this
+               interface is to provide more detailed information for FPGA
+               programming errors to userspace. This is a list of strings for
+               the supported status.
+
+               * reconfig operation error      - invalid operations detected by
+                                                 reconfiguration hardware.
+                                                 e.g. start reconfiguration
+                                                 with errors not cleared
+               * reconfig CRC error            - CRC error detected by
+                                                 reconfiguration hardware.
+               * reconfig incompatible image   - reconfiguration image is
+                                                 incompatible with hardware
+               * reconfig IP protocol error    - protocol errors detected by
+                                                 reconfiguration hardware
+               * reconfig fifo overflow error  - FIFO overflow detected by
