Subject: [PATCH] configs: colibri-imx7: Fix bad block table in flash
configuration
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.
Upstream-Status: Submitted [https://lore.kernel.org/all/20230210103351.22907-1-francesco@dolcini.it/]
Fixes: fd8c1fc9430 ("arm: dts: imx7: colibri: add raw NAND support")
