From: Scott Wood Date: Wed, 10 Apr 2013 22:34:37 +0000 (-0500) Subject: mtd: fsl_ifc_nand: set NAND_NO_SUBPAGE_WRITE X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=20cd0008bb01ea0f5dd5779896bf6f069aab9c8a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git mtd: fsl_ifc_nand: set NAND_NO_SUBPAGE_WRITE This controller only does ECC on full-page accesses, even though the ECC consists of multiple steps. fsl_elbc_nand can get away with this because the ECC of an all-0xff region will be all-0xff, but this is not true with the ECC algorithms used by IFC.
