Start of felsunxi.class, binds with Allwinner SoC when SoC is in FEL mode
 - Idea with this is to make it a Aros installer for Allwinner SoCs
 - Porting Aros to Allwinner SoC has a problem that we would need UBoot (or equivalent bootloader) that is specially build for one platform and one platform only (eg. pcDuino to setup the hardware)
 - We are trying to bypass the problem by not using UBoot at all, instead we will install generic Allwinner Aros port directly to NAND and the installer gives user the opportunity
 to inform bootstrap about the hardware with Zune GUI that pops up (debug serial port, dram size, dram speed, NAND size, power IC etc.)
 - Information is then written on a structure to some NAND location where the bootstrap code finds it...
 - All platform dependand code will be removed from arm-aros-sunxi, instead a generic build is setup and all needed modules will be installed with the said installer to NAND
