From 294cca6ce5cf5b15ce4ebda4c266b4a849735c65 Mon Sep 17 00:00:00 2001 From: Pratyush Yadav Date: Tue, 1 Dec 2020 15:57:11 +0530 Subject: [PATCH] mtd: spi-nor: spansion: Set ECC block size The S28 flash family uses 2-bit ECC by default with each ECC block being 16 bytes. Under this scheme multi-pass programming to an ECC block is not allowed. Set the writesize to make sure multi-pass programming is not attempted on the flash.
