tools: socfpga: image installation script
Installing u-boot on socfpga is not trivial. Yes, it can be done with dd, but it is easy to make a typo and destroy a partition. Introduce a script that knows how to install all the copies, and actually checks signatures so that killing data is not trivial.

This u-boot-spl.img and u-boot-dts.img is superseded by u-boot-with-spl.sfp for a long time. You can just dd that to partition 0xa2 and be done with it, no need to manually do what U-Boot buildsystem does for you.
