-Subject: [PATCH 157/203] mtd: nand: pxa3xx: Consolidate ECC initialization
-
-In order to avoid code duplication, let's consolidate the ECC setting
-for all SoC variants. Such decision is based on page size and ECC
-strength requirements.
-
-Also, provide a default value for the case where such ECC information
-is not provided (non-ONFI devices).
-
