Thanks for the response.
For platform bus, you can match by id or by name :

You are right, the platform_match() does not succeed based on a simple

You could try defining YAFFS_IGNORE_TAGS_ECC in fs/yaffs2/yaffs_ecc.h
and give it a shot. If this works it would mean, h/w ECC uses up the OOB
spare area leaving no space
for YAFFS2 to mark bad blocks hence showing 100% usage.
