Subject: [RFCv3 2/3] mtd: Add pairing info for Toshiba TC58TEG5DCLTA00 NAND
Date: Wed, 29 Sep 2021 10:09:48 -0500 [thread overview]
Message-ID: <20210929150949.198-3-macroalpha82@gmail.com> (raw)
In-Reply-To: <20210929150949.198-1-macroalpha82@gmail.com>
From: Chris Morgan <macromorgan@hotmail.com>
Add pairing info for the Toshiba TC58TEG5DCLTA00 NAND so that we may
utilize slc-mode emulation for enhanced reliability and compatibility
with upstream Linux.
