Kinetis port of Ethernut (Nut/OS)
Idea is to use existing code for Context switching (used for STM32), Freescale (NXP) SoC peripheral drivers (MCU Xpresso SDK) and add Nut/OS driver "wrappers", reuse chip drivers used in an application running on MCF52259 cpu (mk68, Coldfire).
Currently found differences: 1) Kinetis needs flash security settings, located at 0x400, 0x10 long. Without this, an application cannot even start, because it cannot read flash address 0 (SP value).
