What: /sys/bus/platform/drivers/zynqmp_fpga_manager/firmware:zynqmp-firmware:pcap/status
Date: February 2023
KernelVersion: 6.4
Contact: Nava kishore Manne <nava.kishore.manne@amd.com>
Description: (RO) Read fpga status.
Read returns a hexadecimal value that tells the current status
of the FPGA device. Each bit position in the status value is
described Below(see ug570 chapter 9).
