am335x: baltos

am335x: baltos

[Yegor Yefremov]

am335x-baltos got broken between 2022.06 and the current master. The
symptoms: no barebox console output at all i.e. the system freezes.

Here is git bisect log but I don't really see the reason for the failure:

There's nothing in this branch that is even compiled on your board, so I
would guess that you gave a wrong answer somewhere during bisecting.
Apart from bisecting again you could enable some debugging:

[*] Low level debug messages (read help)
    Kernel low-level debugging port (AM33XX Debug UART)  --->
    (0) OMAP Debug UART Port Selection
    [*] Trace initcalls

Regards,
  Sascha

I always forget about this feature. So, the problem was "Compressed
data violation". Changing to CONFIG_CONSOLE_SIMPLE to reduce the NLO
size helped.

Thanks.
