UART0 and/or UART1 interfaces in OpenWRT

How do I enable UART0 and/or UART1 interfaces in OpenWRT?
To use UART1 and UART0 in Linux, you will need two stages
1. enable pinmux so UART0 and UART1 pins are convert into UART mode.
2. enable driver to use UART0 and UART1.
You will need to modify mt7628an_vocore_vocore2.dts or mt7628an_vocore_vocore2.dtsi in openwrt source code to enable them(need to compile new firmware)
Add this
&uart0 {
status = "okay";
};
&uart1 {
status = "okay";
};
&uart2 {
status = "okay";
};
