From a8c7ffdb5fdde3a57c0b654f66f4d81325abe69f Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Thu, 27 Aug 2020 10:51:56 +0200 Subject: mtd: nand: Introduce the ECC engine framework Create a generic ECC engine framework. This is a base to instantiate ECC engine objects. If we really want to be generic, bindings must evolve, so here is the new logic. The following three properties are mutually exclusive: - The nand-no-ecc-engine boolean property is set and there is no ECC engine to retrieve. - The nand-use-soft-ecc-engine boolean property is set and the core will force using the use of software correction. - There is a nand-ecc-engine property pointing at a node which will act as ECC engine. It the later case, the property may reference: - The NAND chip node itself (for the on-die ECC case). - The parent node if the NAND controller embeds an ECC engine. - Any other node being an external ECC controller as well.
