11/21/2017

A few updates in the nvdla hardware tree, most notably moving further development on the non-configurable NVDLA implementation to its own stable branch, nvdlav1, and renaming the full-precision non-configurable implementation to nv_full. The master branch, from now on, will contain potentially-destabilizing ongoing effort for a configurable NVDLA. Note that the default branch has changed, and users may wish to modify which upstream branch they are tracking.

This release includes bugfixes for Xilinx Vivado and Mentor Questa simulators.
