|- |UBOOT_DTB_DEFAULT|| The imx-boot images contain a FIT image with one or more U-Boot device tree files. Currently, signed imx-boot images can contain only a single device tree file.

To select the right U-Boot device tree:

# For dt8mcustomboard board:
UBOOT_DTB_DEFAULT = ""

# For symphony board
UBOOT_DTB_DEFAULT = ""

|- |KERNEL_DTB_DEFAULT||Required for i.MX8QM and i.MX8QXP Family Only

Like imx-boot, currently only a single Linux device tree can be signed. Below is an example of how to perform this signing:

# mx8qm family:
KERNEL_DTB_DEFAULT = "imx8qm-var-som-lvds.dtb"

# mx8qxp family:
KERNEL_DTB_DEFAULT = "imx8qxp-var-som-symphony-sd.dtb"
