Why? Drop the line... or convert it to disabled. Otherwise, why every
SoC has serial0 enabled? Is it used internally?

uart0 is on all the way since this SoC booting from the MaskROM boot code,

load arm-trusted-firmware, load bootloader, and finally load linux  kernel.

uart0 is also the Linux console.
Are you sure? Maybe my board has UART0 disconnected.

Best regards,
Krzysztof


OK, I will have the uart0 disabled in dtsi, and enabled it in dts.


Best regards,

Jacky Huang
