> Understood.  AMD will need to upload a new PSP, but this will at least prep and enable it.

I’d be nice, if you updated the commit message, once your tests are done.

PS5, Line 148: # Don't use AMD's Secure OS if ChromeOS build.
Commit 09abb879a41a (mainboard/google/kahlee: Don't use AMD's secure OS, Change-Id https://review.coreboot.org/c/coreboot/+/31890) [1] does not give a reason, why it’s disabled.

If possible, it’d be great if you extended the comment.
