Re: [U-Boot] [PATCH] Makefile: Only build dtc if needed

At present U-Boot always builds dtc if CONFIG_OF_CONTROL is defined. This is wasteful when the system already has a suitable version available.

Update the Makefile logic to build dtc only if the version available is too old.

This saves about 3 seconds of CPU time on a clean build for me.

Nice !
