[U-Boot] [PATCH] arm: at91: gardena-smart-gateway-at91sam: Enable CONFIG_SYS_NAND_USE_FLASH_BBT

[Stefan Roese]

This patch enables the BBT in NAND on the AT91SAM based GARDENA smart
Gateway. This is especially important, since the Linux driver also
enables this option and uses the BBT table pages. Without setting this
option, U-Boot will try to re-use these pages again (e.g. UBI).

Eugen, I would advise you to double-check, if your AT91 based boards
using NAND also have this BBT option enabled in Linux. If yes, its
definitely necessary to enable it in U-Boot as well to match the same
layout.
