Any comments on that series? I would appreciate to get the BCH8 support
in for at least the tricorder board.

We used that patchset for a while in-house and could not find obvious
issues. However we need to hack the SPL a bit to get the bigger
footprint into SRAM with 2013.01.
I would really appreciate if some other omap users could test it.
One thing is that most current NAND (even SLC) devices require at least
4Bit ecc for most sections.

So my question here is if this series would be accepted for the upcoming
release. I could work on it next week full time, so if I get a go for
this release I would do so.
