Nice I also did a driver for this but I hardcoded everything so it was
useless for anyone but me(and mostly for me too ).

Is arm little endian?? one reason I did not find this so useful for me
was that I have a powerpc target and that is big endian and I could not
use it for jff2 work as the data would not work when moved from a pc to
the target.

Nice you parse the CIS data I never got around to do that. 
Any thought on partitions as I understand it you only get one region.
Perhaps creating a device node and some ioctl could solve that but It's
maybe not that important.

I'm going to test this out but I'm in the middle of some other work so
it has to wait some time.
