Subject: [PATCH v4 0/3] mtd: Support slc-mode for NTC CHIP
Date: Thu, 16 Dec 2021 12:44:45 -0600 [thread overview]
Message-ID: <20211216184448.27193-1-macroalpha82@gmail.com> (raw)
From: Chris Morgan <macromorgan@hotmail.com>
Add support for slc-mode implemented in Linux for the Toshiba
TC58TEG5DCLTA00 NAND and Hynix H27UCG8T2ETR NAND flash found on the NTC
CHIP. This requires the addition of a paired-pages scheme, a new
parameter for MTD partitions of slc-mode, and setting the correct
paired-pages scheme for the TC58TEG5DCLTA00 and H27UCG8T2ETR flash
chips.
Changes since V3:
- Rebased against master branch as of 2021-12-16.
- Added slc mode support for mtdparts command.
Changes since V2:
- Copied upstream Linux implementation of mtd_erase to fix an issue
with creating new ubi partitions.
- Implemented paired page scheme and added support for Hynix flash
chip. Based on a cursory reading of the datasheet it appears to use
the same pairing scheme as the Toshiba chip.
Changes since V1:
- Updated mtd_read and mtd_write to match upstream Linux.
- Additional mtd_get_master to match upstream Linux.
- Removed notes about ubifs not working, because it is now.
