mmcroot in U-Boot 2022.04 vs 2023.04

[dpog]

I recently switched from u-boot-imx 2022.04 to 2023.04, and I'm curious about the header file. 

In 2022.04 the mmcroot env var is set by using CONFIG_MMCROOT "/dev/mmcblk1p2", which is working fine, and when I boot from the eMMC, this is changed to mmcblk2p2. In 2023.04 however, the variable is directly set to /dev/mmcblk1p2. Is there a way I can reproduce the 2022 behaviour in 2023?

You could try to modify the u-boot source code to add the CONFIG_MMCROOT back.
