Subject: qconfig: Support a 'list' format
X-Git-Url: http://git.dujemihanovic.xyz/html/index.html?a=commitdiff_plain;h=00b0855aef3c6d14a435d33a799a0649cda34e5c;p=u-boot.git

qconfig: Support a 'list' format

Add a flag to output the found list in a more user-friendly format, with
one board per line. Omit the board count.

This can be useful with grep, for example.
