From 6d7604e517bc00a36ebf7ffb4973fb72823be18c Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Tue, 12 Aug 2014 08:54:56 +0800 Subject: [PATCH] mtd: spi-nor: add support for s25fl128s We need to store the six bytes ID for s25fl128s, since it shares the same five bytes with s25fl129p1. This patch adds a macro INFO6 which is used for the six bytes ID flash, and adds a new item for the s25fl128s.
