From d92fdb60677b3990919a4216d3452418db215224 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Fri, 1 Nov 2024 10:17:54 +0100 Subject: [PATCH] binman: Add option for pointing to separate description Adding binman node with target images description can be unwanted feature but as of today there is no way to disable it. Also on size constrained systems it is not useful to add binman description to DTB. Introduce BINMAN_DTB Kconfig symbol which allows separate DTB for target from DTB for binman itself.
