Currently I try to rebase this patch to v2020.10. But still run into
crashes. After some fun with bisect I could blame this commit:

commit 09140113108541b95d340f3c7b6ee597d31ccc73
Author: Simon Glass <sjg at chromium.org>
Date:   Sun May 10 11:40:03 2020 -0600

    command: Remove the cmd_tbl_t typedef


09140113108541b95d340f3c7b6ee597d31ccc73 BAD
691d719db7183dfb1d1360efed4c5e9f6899095f GOOD

But I assume that I need to fix something on my patch. Perhaps someone
could comment and help me on this.

Best regards,

Oliver
