Subject: Re: [PATCH] ARM: at91: remove at91sam9rl legacy board support
On 01/10/2014 18:41, Alexandre Belloni :
> Remove legacy support for at91sam9rl boards.
> This include board files removal plus all legacy code for non DT boards
> support.
I add a little sentence, just to avoid confusion:
"Use the Device Tree for running this board with newer kernels."

Now I queue it on top of at91-3.18-soc3
Thanks, best regards,
