I'm trying to get it to work with Buildroot. Buildroot does have a
package for uboot-tools, so I could use that to run it. I'd have to
move the config and build commands into Buildroot's uboot package.
Since the script belongs to U-Boot anyway, it seemed cleaner to
integrate it directly into U-Boot so it could be used by other build
systems too.
