To support optee-os and trusted-firmware-a, update ITS file generation scripts, so users are able to use u-boot FIT image to load u-boot, optee-os and treustred-firmware-a images Add a variable "UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A" to enable trusted-firmware-a image and it is disable by default. Add a variable "UBOOT_FIT_OPTEE_OS" to enable optee-os image and it is disable by default. The ITS file creation loos like as following. 1. Both optee-os and trusted-firmware-a are disabled. ''' /dts-v1/; / { images { uboot { }; fdt { }; }; configurations { default = "conf"; conf { loadables = "uboot"; fdt = "fdt"; }; }; }; ''' 2.
