From 9c9f32eddee56888c7acd0d69134a5dcae09e1a8 Mon Sep 17 00:00:00 2001 From: Alessandro Rubini Date: Wed, 12 Jun 2013 09:13:25 +0200 Subject: [PATCH] FMC: create drivers/fmc and toplevel Kconfig question This commit creates the drivers/fmc directory and puts the necessary hooks for kbuild and kconfig. The code is currently a placeholder that only registers an empty bus. Signed-off-by: Alessandro Rubini Acked-by: Juan David Gonzalez Cobas Acked-by: Emilio G.
