Falcon mode loads a kernel file and an args file which is the device-tree. However in the case of kernel file being a FIT that contains the device-tree within it, loading the args file is not required. Therefore, this patch introduces a new SPL_OS_BOOT_ARGS config options that allows us to enable or disable loading of the args file in falcon mode. Signed-off-by: Anshul Dalal <anshuld@ti.com>
