From: Alan Tull <atull at opensource.altera.com>

This patchset adds two chunks plus documentation:
 * fpga manager core: exports ABI functions that write an image to a FPGA
 * DT Overlay support: simple-fpga-bus to handle FPGA from a DT overlay

The core's ABI is minimal to start with: only 6 functions.  This gives a
common interface for programming various FPGA such that any higher level
interfaces such as the DT Overlays or anything else that is added can be
shared and not be manufacturor-specific.

The DT Overlays support exists for the usage where the FPGA will contain
some "hardware" that will need drivers.  Where that use model is not
appealing, the core ABI can be used to add a different use model such as
using an FPGA as acceleration as has been discussed.

This patchset gets rid of the sysfs controls that allowed direct
control of a FPGA from userspace.

This patchset is under drivers/staging as the interface could change.

The bindings for the socpfga fpga manager already are upstreamed as

The DT Support is dependent on Pantelis's dtc overlay patches from
https://github.com/pantoniou/dtc.git
and his DT overlays configfs interface patches and fixes from
https://github.com/pantoniou/linux-beagle-track-mainline
