[U-Boot] tools: socfpga: image installation script

[Pavel Machek]

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This u-boot-spl.img and u-boot-dts.img is superseded by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.
