This patch provides four configurations which can support U-Boot SPL to boot from RAM or FLASH and then boot FIT image including OpenSBI FW_DYNAMIC firmware and U-Boot proper images from RAM or MMC boot devices. With ae350_rv[32|64]_spl_defconfigs: U-Boot SPL will be loaded by gdb or FSBL and runs in RAM in machine mode and then load FIT image from RAM device on AE350. With ae350_rv[32|64]_spl_xip_defconfigs: U-Boot SPL can be burned into SPI flash and run in flash in machine mode and then load FIT image from SPI flash or MMC device on AE350.
