Dear Gianfranco,

we are currently developing a board based on AT91SAM9G20 on a mini-pci form factor. We'd like to distribute all the documents (i.e. schematics, bom, gerber, etc.) freeware as well as all the patches of u-boot and linux in order to have this board included into the main trees.
I can speak for U-Boot only. The ARM Linux kernel tree is a different story.
My questions are: 1) do we need any authorization or registration to do this? 2) what other requirements shall we respect to be included into the main trees (u-boot and linux)?
1) No, you do not need any authorization or registration. this is Free Software, and you are welcome to usae and enhance it in any which way you want.
2) Mind the hints at http://www.denx.de/wiki/U-Boot/CodingStyle and http://www.denx.de/wiki/U-Boot/Patches
Best regards,
Wolfgang Denk
