From a881537dfaf281bfcb94313d69dcf9ef8fc89afe Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 19 Apr 2021 11:03:50 -0300 Subject: Revert "mtd: rawnand: bbt: Skip bad blocks when searching for the BBT in NAND" This reverts commit bd9c9fe2ad04546940f4a9979d679e62cae6aa51. Since commit bd9c9fe2ad04 ("mtd: rawnand: bbt: Skip bad blocks when searching for the BBT in NAND") the bad block table cannot be found on a imx27-phytec-phycard-s-rdk board: Bad block table not found for chip 0 Bad block table not found for chip 0 Revert it for now, until a better solution can be found.
