[Buildroot] [PATCH 0/4] LEGO MINDSTORMS EV3 Updates

[David Lechner <david@lechnology.com>]

Hi,

I saw that you have EV3 support using the ev3dev kernel (I'm the ev3dev
maintainer). Here are some updates for better EV3 support in Buildroot.

Earlier this year, I submitted a patch to U-Boot for EV3 support, so we can
now use mainline U-Boot for EV3.

Also, following up from a recent Buildroot email thread, I have added a script
to create usable images using the genimage tool. I also added a linux extension
for the ev3dev drivers. We use them as a git submodule in our kernel, but since
buildroot doesn't seem to be able to handle that, this accomplishes the same
result.

FYI, I am also working on mainline linux kernel support for the EV3, so maybe
around 4.10 or 4.11, we can switch to a mainline kernel here and it will
actually boot. If you don't want to include the ev3dev kernel extension stuff,
that is OK. I assume no one is using Buildroot much with the EV3 at this point
anyway.
