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.
Hi Stefan,
Thank you for the patch. I will look into it with help of Tudor and provide some feedback.
Eugen
