Do you have those errors with the default configuration? On a RPI 4,
this only happens when setting uart_2ndstage to 1 in config.txt.
According to the documentation, this option enables diagnostic
information from the main firmware.

Unless this is different on RPI 1B, this means we are talking about a
warning that happens when enabling diagnostic information, so I am not
sure it warrants a change to stable kernels.

Aurelien
