Subject: [PATCH] nand_base: fix chipsize for multi LUN nands
Date: Mon, 24 Jun 2013 14:08:42 +0200	[thread overview]
Message-ID: <1372075722-9872-1-git-send-email-j.weitzel@phytec.de> (raw)

Chipsize didn't take number of LUNs into account. Sync chipsize calculation
to kernel commit 63795755
Tested with MT29F8G16ADBDAH4 on OMAP4
