Using SCU-UART as UART Debug on Uboot and Kernel

[Jack-Cha]

Hi i.MX champ

A customer would like to use SCU-UART as main debug port on Uboot and Kernel debug.

Can you please let us know if SCU-UART can be used for a UART Debug Port on Uboot and Kernel log message in addition to earlier bring up message from SCFW.

This is asked since 4x UART ports need to be used for extenel device control interface.

Thanks.

Regards, 

Jack
