Console baud rate

Uboot uses speed of 115200bps for console output but default openwrt configuration switch it to 57600bps. To change this parameter you have to go to vi ./target/linux/ramips/dts/mt628an.dtsi and then change bootargs = "console=ttyS0,115200 ";

It seems that this is possible by only editing menuconfig but I didn't find a way so far. Here is a partial tutorial in that purpose https://wiki.openwrt.org/doc/recipes/serialbaudratespeed#second.method
