Sorry, in my mind koelsch legacy is already gone ;-)

Only the ones where the DTS is shared between legacy and
reference/multi-platform.
Armadillo is not affected, as the console parameters are kept to have
output on both graphical and serial console.
So that leaves us with lager and koelsch only.

Do you want me to resend with the console= parameter kept for koelsch
and lager?
Or should we delay this whole series until koelsch and lager legacy
have been dropped?
IIUC, this is going to happen soon for koelsch, but not for lager?
Thanks!
