| Linux kernel FPGA support |

| Alan Tull 2017 |

| The main point of this project has been to separate the out the upper layers |
| that know when to reprogram a FPGA from the lower layers that know how to |
| reprogram a specific FPGA device. The intention is to make this manufacturer |
| agnostic, understanding that of course the FPGA images are very device specific |
| themselves. |
| |
| The framework in the kernel includes: |
| * low level FPGA manager drivers that know how to program a specific device |
| * the fpga-mgr framework they are registered with |
| * low level FPGA bridge drivers for hard/soft bridges which are intended to |
| be disable during FPGA programming |
| * the fpga-bridge framework they are registered with |
| * the fpga-region framework which associates and controls managers and bridges |
| as reconfigurable regions |
| * the of-fpga-region support for reprogramming FPGAs when device tree overlays |
| are applied. |
| |
| I would encourage you the user to add code that creates FPGA regions rather |
| that trying to control managers and bridges separately. |
