 5The main point of this project has been to separate the out the upper layers
 6that know when to reprogram a FPGA from the lower layers that know how to
 7reprogram a specific FPGA device.  The intention is to make this manufacturer
 8agnostic, understanding that of course the FPGA images are very device specific
 9themselves.

11The framework in the kernel includes:
12* low level FPGA manager drivers that know how to program a specific device
13* the fpga-mgr framework they are registered with
14* low level FPGA bridge drivers for hard/soft bridges which are intended to
15  be disable during FPGA programming
16* the fpga-bridge framework they are registered with
17* the fpga-region framework which associates and controls managers and bridges
18  as reconfigurable regions
19* the of-fpga-region support for reprogramming FPGAs when device tree overlays
20  are applied.

22I would encourage you the user to add code that creates FPGA regions rather
23that trying to control managers and bridges separately.
