Shouldn't that message become conditional in some way?
You are right, I did something similar on ARM but looks like I missed it on
RISCV.
How is this hunk even useful? Under what conditions can you boot
without a DTB? Even with a built-in DTB, the DT cmdline handling would
be called.
Don't know, I wanted to keep as is today.
Do you think the hunk should be completely removed ?
