|Gateworks uses the OpenWrt Linux Distribution for its Board Support Package (BSP). From time to time, Gateworks may have patches against upstream OpenWrt to support some features which have not made it upstream or perhaps are not suitable for upstream OpenWrt. Additionally Gateworks provides a Makefile wrapper around OpenWrt to aid in pinning versions of Opensource tree's to versions that Gateworks has tested with. Please do not allow this to dissuade you from building mainline OpenWrt, particularly if being current version is of importance. There are only a small number of features you will find in Gateworks-OpenWrt that do not exist in mainline, generally related to the GSC.
