2021.10 u-boot broken on emmc

[jiyong]

I just spent a while troubleshooting and I didn't see any post.

The most recent u-boot release, 2021.10, doesn't work for booting from the emmc. It works fine on the sd card with emmc disabled.  Here's the error that it sends over serial:

Someone reported it on the u-boot mailing list but it hasn't gotten much follow up

I think very few people update U-Boot, but it looks like it is better people don't update to U-boot 2021.10.
Thanks for the report.
