If change of baudrate is required then the .config needs to changed and u-boot recompilation is required or the u-boot environment needs to be updated. To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial. So, the environment also needs to be updated with the dtb baudrate to avoid the glitches on the serial.

This needs to be in rST and under doc/ somewhere (and make htmldocs happy).
Any other issue with implementation? M
