It is heartening that they are finally wisening up for their MLC. I
don't believe Toshiba has plans to support this on their SLC, but we
can't have everything! SLC is more stable anyway, I think.

Other than my comments on patches 2 and 4, ack'd by me. Thanks for the
work.
BTW, it looks like a few Micron parts I have actually support both ONFI
and JEDEC parameter pages. I'll see if I can test this out on them.
