I need to disable serial port logs completely from uboot and kernel. Though I can disable logs by adding bootargs as console=null, not able to find mechanism to disable uboot log. Any idea on this?
Thanks Eric for suggestion.
See this patch and thread on the U-Boot mailing list:
[U-Boot] [PATCH 07/32] nitrogen6x: Allow U-Boot to be silent on UART2
Our patch does the simple thing: re-muxing the UART pads. Stefano's
suggestion is to use CONFIG_SILENT_CONSOLE
