[PATCH 0/4] mtd: nand: Add support for Evatronix NANDFLASH-CTRL
From: Ricard Wanderlof
Date: Thu Jun 02 2016 - 03:46:45 EST
This patch set adds a driver and relevant devicetree bindings for the
Evatronix NANDFLASH-CTRL NAND flash controller IP. This controller is
used in the Axis ARTPEC-6 SoC.
The driver supports BCH ECC using the controller's hardware, but there is
also an option to use software BCH ECC. However, the ECC layouts are not
compatible so it's not possible to mix them. The main advantage to using
software ECC is that there are more OOB bytes free, as the hardware is
slightly wasteful on OOB space.
BCH ECC from 4 to 32 bits over 256, 512 or 1024 byte ECC blocks is supported.
Only large-page flash chips are supported, using 4 or 5 address cycles.
The driver has been extensively tested using hardware ECC on 2 Mbit flash chips,
with 8 bit ECC over 512 bytes ECC blocks.
