[Buildroot] [PATCH 0/3] LEGO MINDSTORMS EV3 updates

[David Lechner]

Here are a few more updates for LEGO MINDSTORMS EV3 based on feedback from my
recent patch to use the mainline kernel [1].

I have boot-tested both the flash image and the SD card image.

[Buildroot] [PATCH 2/3] lego: ev3: Use genimage to rename uImage file

[David Lechner]

This uses a genimage feature to rename the uImage file instead
of manually creating a symlink in the post-image script.
