I have 2 things to say about this:
1. In theory we can also question why the initial boot delay was 
selected to be 1s.
2. You imply that the "users" want ultra-fast boot times for riotboard. 
Being myself one of the riotboard users, I can assure you that such 
generalization is excessive.

This is a good idea in general, I don't mind it.

Well, this is again subjective - we can always argue that 2s is both too 
long and too short for selected use cases, so I don't understand the 
qualification "less unreasonable".

In summary - I won't carry a war for this change, as it doesn't worth 
it. I just tried to contribute a tiny bit of improvement to the already 
excellent work of Eric, so we can have a silk-smooth out-of-the-box 
U-Boot user experience, and I'm doing this as an actual riotboard user. 
That's all.

Thanks for sharing your viewpoint.

Kind regards,
Nikolay
