Orange Pi R1 Plus and LTS don't have eMMC (default mmc0 in rk3328-u-boot.dtsi). The device is equipped with SPI flash memory, which U-Boot tries to use for reading configuration. However, the manufacturer has not provided any means to utilize SPI flash memory. There is no documentation, or software available for this purpose.
The U-Boot documentation contain limited information on how you can write the generated rockchip-u-boot-spi.bin to SPI flash, after that it will load U-Boot from the SPI flash instead.
https://docs.u-boot.org/en/latest/board/rockchip/rockchip.html#spi
As a result, during OpenWRT sysupgrade, the board fails to boot because the script that switches the boot_device to an available one does not trigger.
This sounds more like an issue in your script?
This patch changes the alias of mmc0 from &emmc to &sdmmc, ensuring the board boots correctly, and sysupgrade completes successfully.
There are aspects of the rockchip U-Boot code that depend on that mmc0 is emmc and mmc1 is sdmmc, so this change may introduce new issues and should be avoided.
I have no issues booting my OrangePi R1 Plus LTS without this. Please explain what the issue is and what script you are referring too. Is this a U-Boot script or linux userspace script? also what version of U-Boot have you had issue with? Does your SPI flash come with a vendor U-Boot that is interfering with your sysupdate?
Additionally, this allows saving the U-Boot environment by using saveenv with uboot-envtool.
U-Boot will expect the environment on the mmc device that U-Boot was loaded from, and fallback on what U-Boot consider is the SD-card (mmc1).
saveenv from U-Boot CLI should work as intended and already save the env to the sdmmc, unless there is other issues/modifications in your U-Boot.
So this may also be an issue in userspace tool?

This is already defined in rk3328-u-boot.dtsi, no need to re-define it here.

It should not be needed to change this, if the emmc node is disabled U-Boot should just skip it. Also the "same-as-spl" should already refer to the SPI flash or the SD-card depending on where TPL/SPL was loaded from.
