11 For the purposes of this API document, let's just say that a region associates
12 an FPGA Manager and a bridge (or bridges) with a reprogrammable region of an
13 FPGA or the whole FPGA. The API provides a way to register a region and to
14 program a region.
16 Currently the only layer above fpga-region.c in the kernel is the Device Tree
17 support (of-fpga-region.c) described in [#f1]_. The DT support layer uses regions
18 to program the FPGA and then DT to handle enumeration. The common region code
22 An fpga-region can be set up to know the following things:
