From bb5925480b13f52ad2e29ab20695c7f27e10f382 Mon Sep 17 00:00:00 2001 From: Frieder Schrempf Date: Wed, 17 Apr 2019 12:36:36 +0000 Subject: mtd: nand: Make flags for bad block marker position more granular To be able to check and set bad block markers in the first and second page of a block independently of each other, we create separate flags for both cases. Previously NAND_BBM_SECONDPAGE meant, that both, the first and the second page were used. With this patch NAND_BBM_FIRSTPAGE stands for using the first page and NAND_BBM_SECONDPAGE for using the second page. This patch is only for preparation of subsequent changes and does not implement the logic to actually handle both flags separately.
