From a3c005506ac87f3684603fc40ada98070027aaa0 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 6 Nov 2018 15:21:31 -0700 Subject: [PATCH] binman: Add a way to enable debugging from the build When the build fails due to something wrong in binman it is sometimes useful to get a full backtrace showing the location of the failure. Add a BINMAN_DEBUG environment variable to support this along with some documentation.
