From: Simon Glass Date: Sat, 20 Jul 2024 10:49:47 +0000 (+0100) Subject: binman: fit: Write the compatible string to configuration X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=57902e6941a0e914313afe50104fd0660ab47839;p=u-boot.git binman: fit: Write the compatible string to configuration FIT allows the FDT's root-node compatible string to be placed in a configuration node to simplify and speed up finding the best match for booting. Add a new property to support this.
