From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bastian Hecht Date: Wed, 26 Sep 2012 09:05:04 +0000 Subject: [PATCH 1/3] mtd: sh_flctl: Probe SNAND_E flag from NAND chip Message-Id: <1348650306-15492-1-git-send-email-hechtb@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-mtd@lists.infradead.org Cc: Magnus Damm , linux-sh@vger.kernel.org SNAND_E indicates whether we deal with 512kB or 2048kB page sizes. We can probe this from the NAND chip itself and don't need to specify it in the platform data anymore.
