Subject: [PATCH 2/2] mtd: nand: Increase NAND_MAX_OOBSIZE
Date: Fri, 20 Aug 2010 12:36:13 -0700	[thread overview]
Message-ID: <1282332973-12077-2-git-send-email-norris@broadcom.com> (raw)
In-Reply-To: <1282332973-12077-1-git-send-email-norris@broadcom.com>

An increase in NAND_MAX_OOBSIZE and NAND_MAX_PAGESIZE is necessary
in order to support many new chips. Among those:

Toshiba TC58TxG4S2FBAxx  8KB page, 576B OOB
Micron MT29F64G08CBAAA   8KB page, 448B OOB
