It has been confirmed that the raw NAND Flash interface on this
yet-to-hit production SoC is only useful for yesterday's parts.
Given the difference in design cycles, this is not surprising
and it provides a number of other managed storage
interfaces (SD/MMC, eMMC, etc..).

In the same phone call, we realized that an 8GB Class 2

longer than normal (it is Slow...) has just become obsolete
--- another quarter, another handful of SD cards to certify...
