+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
+ reconfiguration hardware
