From bcf8c7e7703bb2bbde66bec26a81fed4be9cd1d4 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Tue, 21 Oct 2014 15:09:21 +0200 Subject: ARM: at91: remove at91sam9rl legacy board support Remove legacy support for at91sam9rl boards. This include board files removal plus all legacy code for non DT boards support. Use the Device Tree for running this board with newer kernels.
