I tried loading system with recent u-boot but it does not work.
Trying some ext4ls shows there is some problem accessing the filesystem.
Not sure if this should be attributed to the ext driver or to the mmc driver or something else entirely.
I haven't tested that myself, but I have seen reports on other platforms that the u-boot ext4 driver has problems with ext4 filesystems which use the "flex_bg" filesystem feature, as that causes certain changes to the on-disk layout compared to ext4 without this feature. From what people have reported, it appears that "flex_bg" is enabled by default on ext4 filesystems created with a recent mkfs.ext4 version.
Reformatting without flex_bg does not seem to have any effect.
However, ls seems to give some random stuff for directories other than / so some similar remapping feature could cause this.
it's csum/64bit, disable it:
mkfs.ext4 -O ^metadata_csum,^64bit
