Hi Gurumoorthy,

Add a /chosen node with stdout-path pointing to serial0 (uart1) to

Without this node, the live DT path in serial_find_console_or_panic()
is skipped and the fallback path is used. Adding the /chosen node makes
the console selection explicit and deterministic, ensuring the correct
serial device is always selected as the console.
Please submit this fix upstream! I can pick it here until the next sync
but I'd like it to at least be on the kernel list.

Changes in v2:
- Replaced the DM_FLAG_PRE_RELOC approach (v1) with adding a /chosen
node in the board-specific U-Boot DTSI overlay, as suggested by
Casey Connolly. This is the standard DT mechanism for specifying
the console device and avoids modifying driver flags.
wanna turn down the verbosity of your LLM?
Kind regards,
