From 6b88293aae7fb78872e5cc1ec36e2f750ae12e38 Mon Sep 17 00:00:00 2001 From: Markus Stockhausen Date: Wed, 10 Sep 2025 14:32:58 -0400 Subject: mtd: nand: move nand_check_erased_ecc_chunk() to nand/core The check function for bitflips in erased blocks will be needed by the Realtek ECC engine driver (which is currently under development). Right now it is located in raw/nand_base.c. While this is sufficient for the current usecases, there is no real dependency for an ECC engine on the raw nand library. Move the function over to a more generic place in core library.
