I'm working on a -Micro these days and I will probably send a defconfig for it. The -Micro must pull a different U-Boot config, so the Buildroot defconfig will be different as well. On the other hand, I _suspect_ the files in boards/olimex/a20_olinuxino_lime can be generalized with minimal effort to encompass both boards. But I cannot confirm that right now.

It's https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME/ I build-tested this patch, I should have a board in a few days and be able to run-test it as well.

Interesting! I don't think there is any noticeable lag copying <7 MB to an SD card... But since defconfigs are supposed to be used as a starting point for real, and possibly large, projects, I'm fine with your suggestion.

Indeed, the tags must start in the first column to b recognised by Patchwork. Regards, Yann E. MORIN.

Indeed. That's intentional, because I didn't want to add the tag to the patch as is, but I wanted to signal to Francois that he can add the tag after making the requested changes.
