seL4 Device Driver Framework

The sDDF aims to provide interfaces and protocols for writing and porting device drivers to run as seL4 user level programs. It currently supports a network device running on iMX8 hardware, reaching near wire speed. It has been built on top of seL4 Core Platform and requires this pull request. The seL4 Core Platform binaries can be built separately and handed to the echo_server makefile.

$ cd echo_server
$ make BUILD_DIR=<path/to/build> SEL4CP_SDK=<path/to/core/platform/sdk> SEL4CP_BOARD=imx8mm SEL4CP_CONFIG=(release/debug)

In order to run the benchmarks, set SEL4CP_CONFIG=benchmark. The system has been designed to interact with ipbench to take measurements.
