Hi,
I'm seeing this problem where booting from Samsung EVO 970 / 980 NVMEs isn't possible with the latest version of u-boot master branch on the RPI CM4 IO-Board, at:
commit 6d3c46ed0e230d999c3f20f7fd4f3a88c03b14ca (origin/master, origin/WIP/05Mar2022, origin/HEAD) Merge: 0444cbbe77 cfcf1952c1 Author: Tom Rini Date: Sat Mar 5 20:46:55 2022 -0500
Unfortunately older revisions don't work with these NVMEs either.
This is what I'm seeing in the logs:

Nvme scan takes about 6-7 seconds to complete and returns 1, without any error logs. Any idea what could be causing this problem? Are there some logs that I could add to help in debugging this?
Thank you
