If we would like to boot from SD card, we have to implement mmc driver in SPL stage, and get a slightly large SPL binary. Rockchip SoC's bootrom code has the ability to load spl and u-boot, then boot. If CONFIG_ROCKCHIP_SPL_BACK_TO_BROM is enabled, the spl will return to bootrom in board_init_f(), then bootrom loads u-boot binary. Loading sequence after rework: bootrom ==> spl ==> bootrom ==> u-boot Signed-off-by: Ziyuan Xu <xzy.xu@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org> Fixed up spelling of U-Boot, boorom, opinion->option, Rochchip: Signed-off-by: Simon Glass <sjg@chromium.org>
