Since U-Boot tools are being built anyways it's much nicer
to use them instead of relying on some of them bein installed
on build host (which might easily not be the case).

HSDK board has preloader that reads SPI flash pages and searches
for a special image header to fetch and load binary.
Add tool, make target (bsp-generate) to generate
update script and u-boot binary image with header for preloader.
Also add script to default environment to apply updates.
