From 245224608b5368c10407da07557e546743d3c489 Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Mon, 27 Dec 2021 09:33:13 +0100 Subject: [PATCH 2/2] mtd: spi-nor: disable 16-bit-sr for macronix Macronix flash chips seem to consist of only one status register. These chips will not work with the "16-bit Write Status (01h) Command". Disable SNOR_F_HAS_16BIT_SR for all Macronix chips. Tested with MX25L6405D.
