We use the spl_board_prepare_for_boot hook to call k3_r5_falcon_prep which is ran after tispl is loaded but before jump_to_image. In k3_r5_falcon_prep, we find the boot media and load the kernel FIT just as standard secure falcon mode (since spl_start_uboot returns 0 now). Once the kernel and args are loaded. Now when the flow goes to jump_to_image, we do the regular pre-jump procedure and jump to TFA which jumps to the kernel directly since we have already loaded the kernel and dtb at their respective addresses (PRELOADED_BL33_BASE and K3_HW_CONFIG_BASE). Overall execution for the R5 SPL after this patch: board_init_r |-> boot_from_devices | +-> load_image (we load tifalcon.bin here since spl_start_uboot | returns 1) | +-> spl_prepare_for_boot | +-> k3_falcon_prep | +-> load_image (we load fitImage here since spl_start_uboot | returns 0 now) | +-> jump_to_image Signed-off-by: Anshul Dalal <anshuld@ti.com>
