Since this patch is applyied on master branch, I have error when I compile with the verbose option V=1.

I don't found a correction for this issue until now... except revert this commit.

For information: I use stm32mp1 platform = ARMv7 32bits
I have the error:

scripts/Kbuild.include:220: *** Recursive variable 'echo-cmd' references itself (eventually).  Stop.
make[1]: *** Waiting for unfinished jobs....
make -f /local/home/frq07632/views/u-boot/scripts/Makefile.build obj=arch/arm/dts dtbs
