From 738cb2a73536fdc2736efe516604bfcd4510dcc2 Mon Sep 17 00:00:00 2001 From: Sandeep Gundlupet Raju Date: Sun, 8 Jan 2023 10:25:35 -0700 Subject: [PATCH] kernel-fitimage: Allow user to select dtb when multiple dtb exists Allow user to select the default DTB for FIT image when multiple dtb's exists. From machine.conf or local.conf user can specify the default dtb for FIT image as shown below. FIT_CONF_DEFAULT_DTB = "board-default.dtb" Also fallback to avaialable dtb when FIT_CONF_DEFAULT_DTB doesn't exits or empty.
