Hi Arnd, thanks for the comments and sorry for the large 'To' list. In my v2 I'll limit to Patrice Chotard (STi maintainer).

Indeed, bootargs can be cleaned up. console is not necessary, however it's going to be hard to get rid of the clk_ignore_unused now and I'd prefer to keep it now, in the same way as for the other sti DTs. > > > +&rng11 { > > + status = "disabled"; > > +}; > > Why do you disable the random number generator? I shouldn't have putted this within the board DT. This rng11 is not available on the STiH418. In the v2 serie I'll had a separate commit to fix the stih418.dtsi instead. Alain > > Arnd
