From a6982e2e262440f551fe4dac0378d2dea76c86f5 Mon Sep 17 00:00:00 2001 From: Juergen Beisert Date: Mon, 8 Sep 2014 11:29:07 +0200 Subject: Add a Firmware programming framework This framework handles a list of registered Firmware programming handlers to unify a firmware programming interface by hiding the details how to program a specific Firmware in its handler. This is created with FPGAs in mind but should be usable for other devices aswell. A user has two possibilities to load a firmware. A device file is create under /dev/ which can be used to copy a firmware to. Additionally a firmwareload command is introduced which can list the registered firmware handlers and also to upload a firmware.
