From: Quentin Schulz <quentin.sch...@theobroma-systems.com>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.

This may be wrong because I found that the mmc0 alias is not the same for all the boards.
Rockchip platform do set SD card alias as mmc0 before no alias used by kernel, and after kernel enable
the use of alias, the different board has different mmc0: arch/arm/dts/rk3588-rock-5b.dts: mmc0 = &sdhci; arch/arm/dts/rk3588-edgeble-neu6b.dtsi: mmc0 = &sdhci; arch/arm/dts/rk3588s-orangepi-5.dts: mmc0 = &sdmmc; arch/arm/dts/rk3588s-rock-5a.dts: mmc0 = &sdhci; arch/arm/dts/rk3588-edgeble-neu6b-io-u-boot.dtsi: mmc0 = &sdmmc; arch/arm/dts/rk3588-edgeble-neu6a.dtsi: mmc0 = &sdhci; arch/arm/dts/rk3588-edgeble-neu6a-io-u-boot.dtsi: mmc0 = &sdmmc; arch/arm/dts/rk3588-quartzpro64.dts: mmc0 = &sdhci; arch/arm/dts/rk3588-evb1-v10.dts: mmc0 = &sdhci; arch/arm/dts/rk3588-orangepi-5-plus.dts: mmc0 = &sdhci; arch/arm/dts/rk3588-nanopc-t6.dts: mmc0 = &sdhci; Thanks, - Kever
