If Falcon mode support is enabled (and the system isn't directed into booting u-boot), it will instead try to load kernel from sector CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR and CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTORS of kernel argument parameters starting from sector CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR.
