If we look at the TS site and what is says about this kernel it clearly states
that NAND flash support is "untested". Since it seems improbable that they
could not find at 7250 to test this on I think this means they tested it and it
DOES NOT WORK.
This has been resolved in more recent mainline kernels.
Sadly this means you'll need to sort out a cross compiler and do the dirty work
yourself. This is a bit of a learning curve if you are not upto speed on cross
compiling but you will need this capability anyway. The root fs image provided
by TS for 2.6.21 is unlikely to work out of the box for a more recent kernel.
There are patch sets in the files section here for upto date kernels that have
much better support for the cyrus arm CPU so this is worth having.
Several people have reported having this working on 7250 , so the good news is
it works, it's just a bit of graft.
