It is possible to boot U-Boot proper from a different storage medium than the one used by the BOOTROM to load the SPL. This information is stored in the u-boot,spl-boot-device Device Tree property and is accessible from U-Boot proper so that it has knowledge at runtime where it was loaded from.
Let's add support for this feature for rk3588 the same way it was done for px30 and rk3399.
