Sorry, I used vim and imported patch as a file in evolution, I
understood too late that I also need to change Format from "normal" to
"preformatted". In the future I will use "git send-email".

Maybe I was wrong in writing "move configuration files.." 

I think [PATCH 0/4] can be consider an atomical change: Fabio first uDoo
support adopt nitrogenx register setting for DDR3, clock, muxing, etc

uDoo schematics is rather different from nitrogen6x, and it needs
customized setting for most of the register (as every platform). It
takes too long describe every single new setting. 
Previous configuration was very unstable and adopting those settings
uDoo board has frequently crash. Seco had validated new setting I'm
going to propose using "climatic room" and various tests, which stressed
system and cpu for about 7 days long cycles.

See above.

Fabio was abreast of this changes, but not in cc. I'll use CC in next
post.
