From af7a74bad1a4bba9fdb348c06436c843c5f287e4 Mon Sep 17 00:00:00 2001 From: Markus Stockhausen Date: Wed, 1 Oct 2025 02:01:48 -0400 Subject: [PATCH] realtek: Enhance MTD/ECC kernel configuration for NAND targets The Realtek NAND kernel configuration has some shortcomings. Fix this as follows: - MTD_NAND_ECC_REALTEK selects MTD_NAND_ECC and this selects MTD_NAND_CORE. For consistency add both config options. - The partition layout of the Linksys switches requires some tricky concatenation to keep dual boot active.
