From 902d9e0f48ddc18fb37c1b1edf5e3b27aaba1505 Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Wed, 8 Aug 2012 19:37:04 +0200 Subject: ssb: check for flash presentence MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We can not assume parallel flash is always present, there are boards with *serial* flash and probably some without flash at all. Define some bits by the way. Signed-off-by: Rafał Miłecki Reviewed-by: Hauke Mehrtens Signed-off-by: John W.
