BUG: U-Boot crashes on SiFive Unmatched when CONFIG_DM_DEBUG=y

Mon Nov 18 21:50:45 CET 2024

Hi all,

I enabled CONFIG_DM_DEBUG on my SiFive Unmatched, and U-Boot boot results in
failed assertion ("ofnode_valid(node)"). I'm attaching the full log below.

The same behavior is also for the 2024.10 stable version.
