I have a problem with the bootstd conversion series.
I have a Buildroot image that boots U-Boot 2025.01 on imx93-evk:

If I flash U-Boot top-of-tree into the SD card, the boot fails:

Even though /boot/extlinux/extlinux.conf was found, it did not succeed
in booting it.
If you want to test the same environment I am using, build a Buildroot image
using mainline Buildroot:
https://github.com/buildroot/buildroot/commit/27b3e6774fe447dc5eb12cc7f498ec8868eb65c9
How can we fix this boot regression? This affects imx8mm-evk,
imx8mn-evk, imx8mp-evk as well.
