current default toolflow uses a proprietary boot copier. we would like to be able to use a standard uboot to boot the nios2 image.
one of the goals for this implementation is to be able to use the bootloader to write to flash so that we do not need proprietary tools to create and program the flash images.
Moved to m3. progressing but more debugging needed.
