[PATCH v1] configs: colibri-imx7: Fix bad block table in flash configuration
From: Stefan Eichenberger stefan.eichenberger@toradex.com
Make sure that the bad block table in flash is used on Colibri iMX7. Without this configuration enabled U-Boot corrupts the bad block table and Linux will update the table on each reboot. The corruption occurs because if CONFIG_SYS_NAND_USE_FLASH_BBT is not set, U-boot will store bad blocks out of band, while the Linux driver for the iMX7 will store them in band in a bad block table.
