You're right, the extended id parsing should take care of that.

Yup, that's also in the extended id parsing.

I have an idea here : as barebox is not performance oriented, and as the timings
are minimum guaranteed times between signal swaps, let me try to hard encode all
timing with their maximum value.

Of course performance will suffer, but as long it remains usable with a loss of
20% or less in throughput, that will be a cool simplification.

Cheers.
