From e4290aa10af0a69c81bbb3be1a8aef7465aed2ad Mon Sep 17 00:00:00 2001 From: Ladislav Michl Date: Sun, 19 Feb 2017 00:24:49 +0100 Subject: [PATCH] igep00x0: fixup FDT according to detected flash type Leave only detected flash type enabled in FTD as otherwise GPMC CS is claimed (and never freed) by Linux, causing 'concurent' flash type not to be probed.
