With CONFIG_SPL_OS_BOOT enabled, U-Boot checks for the return value of spl_start_uboot to select between falcon or the regular boot flow. With a return value of 0 implying falcon mode.
This patch overrides the weak definition form common/spl/spl.c to allow K3 devices to use falcon mode with SPL_OS_BOOT enabled.
