u-boot top makefile

[Val Shkolnikov]

Hello,
I would like to modify the top Makefile target scripts_dtc recipe. 
Currently, it's a long shell command. I'd like to separate it into a 
script in the scripts directory. The scripts of this length should not 
be coded directly in the makefile. In this particular case if $Q is 
unset (vebose mode), the whole recipe is echoed. Also echoed an "Error: 
" string coming from the scripts/dtc-version.sh called in the recipe. 
This confuses error detection tools used in our organization.
Regards,
