From 193fb3c1127d0c0fbc5c5a6ba63a99083b775ffd Mon Sep 17 00:00:00 2001 From: "mar.krzeminski" Date: Fri, 6 Jan 2017 18:19:01 +0100 Subject: mtd: spi-nor: Disable chip erase for Micron n25q00. Micron n25q00 are stacked chips, thus do not support chip erase. >From now spi-nor framework will not send chip erase command, instead will use sector at time erase procedure.
