Subject: mtd: nand: Increase NAND_MAX_OOBSIZE
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5c709ee9f33da4a07d94e3d48b297eb6f003fc61;p=openwrt%2Fstaging%2Fblogic.git

mtd: nand: Increase NAND_MAX_OOBSIZE

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
