+Cc Chris who maintains this board and may be able to help.
I somehow didn't receive this mail in my inbox, here's my attempt at
quoting text from a mail I didn't receive (and it's also not available
on lore.kernel.org...).

If you have a known working version of U-Boot, maybe start a bisect with
that commit as good and 2026.07 as bad to isolate a commit that broke
the board.
