I don't think so, I observed same behavior with sheevaplug,
i.e. "nand_bbt: Can't scan flash and build the RAM-based BBT" message in nand init
which was okay before this git pull

Yes, the build might be with this defined "yes", without this build throws error message

I didn't see any warning on sheevaplug

This is openrd board, not yet mainlined, it is derived from sheevaplug, (nand is similar)
Alternately you can refer sheevaplug.h since problem is on sheevaplug too.

I tried removing this patch and things are normal on sheevaplug
