4 The FPGA subsystem supports reprogramming FPGAs dynamically under
5 Linux.  Some of the core intentions of the FPGA subsystems are:
7 * The FPGA subsystem is vendor agnostic.
9 * The FPGA subsystem separates upper layers (userspace interfaces and
11   FPGA.
23 FPGA Manager
26 If you are adding a new FPGA or a new method of programming an FPGA,
27 this is the subsystem for you.  Low level FPGA manager drivers contain
32 FPGA Bridge
35 FPGA Bridges prevent spurious signals from going out of an FPGA or a
36 region of an FPGA during programming.  They are disabled before
37 programming begins and re-enabled afterwards.  An FPGA bridge may be
39 bridge in FPGA fabric that surrounds a partial reconfiguration region
40 of an FPGA.  This subsystem includes fpga-bridge.c and the low level
43 FPGA Region
46 If you are adding a new interface to the FPGA framework, add it on top
47 of an FPGA region.
49 The FPGA Region framework (fpga-region.c) associates managers and
51 FPGA in full reconfiguration or to a partial reconfiguration region.
53 The Device Tree FPGA Region support (of-fpga-region.c) handles
