Not that I know of (unless something in cmd_yaffs2.c can do it).

That was several years ago; if someone wants to submit a proper patch 
against current u-boot (without the pre-2.6.18 support, or at least with 
the newer format being the default), I'll apply it.  Better yet would be 
a more general mechanism whereby the user specifies how many OOB bytes 
are interleaved in the supplied image, without any specific knowledege 
of yaffs.
