Does the Linux kernel driver use those unconditionally or is that a kernel config option? Which one? (Search in 5.2 kernel config for BBT is inconclusive.) Linux uses the DT property "nand-on-flash-bbt" for this decision. But please be aware - this is only for raw NAND and not SPI NAND (IIRC). And yes, we should definitely move to this DT property instead of the Kconfig symbol in U-Boot as well. To automatically match the configuration of such boards in U-Boot and Linux. But such a change it too intrusive at this time of release cycle. Thanks, Stefan ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot

Signed-off-by: Stefan Roese Cc: Eugen Hristev Cc: Tom Rini --- 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. Do you have any updates on this? Would it be possible to apply this patch for the upcoming release? Thanks, Stefan Applied to u-boot-atmel/master Thanks. Will queue it before release in a PR. Have to check if more at91 boards need the same kind of patch. As mentioned before, I'm pretty sure that most (all) at91 boards with NAND need this patch.
