Perhaps I should know this, but I don't and cannot find it written down anywhere...

How do I initalize an ETFS file system, including configuring it to leave some parts of the NAND out of the file system

e.g.

There is a 128MB  NAND device at 0x40000000
At offset 0 is the IPL and IFS for 10MB of space

How do I initialize the ETFS filesystem, and specify that I want to use 16MB at offset 0x100000 in the NAND i.e. skip 
the first 16MB so that is unmanaged by devf-etfs ? Can I do this ?

etfsctl is still documented as being for RAM and SRAM only - is that correct ?

Once initialized, what do I need to specify when I start the driver so that it finds the filesystem ? Assuming I only 
specify the base addres of the Flash, how does it find the filesystem ?

Thanks
