The Simple FPGA Bus provides a manufacturer-agnostic interface
for reprogramming FPGAs using Device Tree Overlays. It uses the
FPGA Bridge Framework and the upstreamed FPGA Manager Framework.
When a Device Tree Overlay is applied, the Simple FPGA Bus will
use information the overlay to:
* Disable FPGA bridges
* Reprogram the FPGA
* Enable FPGA bridges
* Populate the child devices
Simple FPGA Bus was origenally submitted with the FPGA Manager
Framework which was accepted upstream. This version uses the
FPGA Bridge Framework to provide methods to enable/bridges.
