The Header Register set is always present for FPGA Management Engine (FME), this patch implements init and uinit function for header sub feature and introduces several read-only sysfs interfaces for the capability and status. Sysfs interfaces: * /sys/class/fpga_region/<regionX>/<dfl-fme.x>/ports_num Read-only. Number of ports implemented * /sys/class/fpga_region/<regionX>/<dfl-fme.x>/bitstream_id Read-only. Bitstream (static FPGA region) identifier number. It contains the detailed version and other information of this static FPGA region. * /sys/class/fpga_region/<regionX>/<dfl-fme.x>/bitstream_metadata Read-only. Bitstream (static FPGA region) meta data. It contains the synthesis date, seed and other information of this static FPGA region.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
