U-Boot can talk to only one serial device at a time anyway, so why
should it intiaalize othe rports than the one used for the (then
current) console?

U-Boot does lazy initializationintentionally.  It is wrong to
initialize devices which are not actually used.

How exactly did you try to do that?

I have a feeling that you attempt to do the Wong Thing.
