From cac0172389688b861d269eb4f1fee679d21a1372 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Tue, 27 Jan 2015 16:41:55 +0100 Subject: ARM: at91: change board files into SoC files As board files are now DT only and can address all aspects of the SoC family, we can rename them so that the mach-at91 directory looks cleaner.
