  10 So far every Northstar device we have seen was using the same serial
  11 console params (115200n8). It probably make the most sense to put it in
  12 some proper dtsi files instead of repeating over and over for every
  13 single device. As different boards may use different bootloaders it
  14 seems the safest idea is to use board specific dtsi files.
  15
  16 Just in case some vendor decides to use different UART (parameters) this
  17 can be always easily overwritten.
