One reason we picked dt in Hamburg was that the binary packed form
was very simple to parse. I don't think the size will be a problem.

Please do not do this. :\ I would consider it a serious regression in

The idea is to stay legacy free in order to avoid constraints and
actively support and further evolution.

Adding (even optional) legacy support into coreboot feels quite
counter-productive. :\

Short-term BIOS support is still needed to be a drop-in replacement.

Slightly-longer-term anything BIOS must be discouraged IMHO.

Kevin, please don't think I dislike your work - it is truly great!
But I do hope that it will be a trampoline to better BIOSless boots
in the near future.
