Good news!

Which board have you targeted initially?
One of my concerns is that the NAND subsystem interfaces are appropriate
for other filesystems (such as UFFS) and for a broad range of NAND
devices. An interim code drop with any existing documentation would be
very welcome to kick-start the discussion.
