Dear Ladislav,

I know how this goes. Been there before. Can't remember when for  the
first time :-(

Can you please either send this by e-mail, or put it on a server that
actually works?

If I add it to "testing-NAND" (and it makes a lot of sense if this is
a working example) then it will go more or  less  automagically  into
the main tree as soon as I merge branches. Is this acceptable to you?

We will have to go through this when switching the code base.

But only one version shall be in the main branch at a time, i. e. one
day the new code will replace the old one, and then all  boards  will
need to be converted.

Will do when I can lay my hands on the patch; keep  getting  timeouts
only :-(

Thanks for providing a sound base for this discussion.
