So I think if you need something that changes the layout from normal operations, it needs to be a new mode. And it's about time to sync up U-Boot's NAND code with Linux again...
Well aren't you the maintainer that should take care of it ? ;-)
Yes, that note was me adding something to my todo list. :-)
I'm not talking about circumventing the driver, just accessing some user OOB bytes through it.
There are no user OOB bytes, the driver does the ECC so user has no need to write any OOB.
By "user OOB bytes" I meant things other than the ECC and the bad-block marker -- the space described by oobavail in ecclayout. This is getting less useful with partial-page restrictions and large ECC that fills up most of the OOB, though, and thus there's a trend away from making use of it. So if it's a pain to provide access to any spare OOB bytes, it's not that big of a deal.
