Subject: [PATCH 1/3] mtd: sh_flctl: Probe SNAND_E flag from NAND chip
Date: Wed, 26 Sep 2012 11:05:04 +0200 [thread overview]
Message-ID: <1348650306-15492-1-git-send-email-hechtb@gmail.com> (raw)
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.
