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. Signed-off-by: Sandeep Gundlupet Raju <sandeep.gundlupet-raju@amd.com> --- Changes in v2: - Add check condition if FIT_CONF_DEFAULT_DTB file doesn't exists and fallback to avaialable dtb in EXTERNAL_KERNEL_DEVICETREE path. --- meta/classes-recipe/kernel-fitimage.bbclass | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-)
