Hi Marek,

Add script to read U-Boot from SD card and write it to matching locations in the SPI NOR, thus making the SPI NOR bootable. The script erases the entire SPI NOR, including U-Boot environment, to make sure the installation is clean. To retain environment from current running U-Boot, run 'saveenv' after running the 'update_sf' script.
