Subject: [PATCH v4 2/2] mtd: spi-nor: Disable chip erase for Micron n25q00.
Date: Fri, 6 Jan 2017 18:19:01 +0100 [thread overview]
Message-ID: <20170106171901.27565-3-mar.krzeminski@gmail.com> (raw)
In-Reply-To: <20170106171901.27565-1-mar.krzeminski@gmail.com>
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.
