The documentation has been overhauled, too. The new NAND layout, with a 
package for Common NAND besides a package for raw NAND, is published on 
http://www.cs.vu.nl/~rutger/software/ecos/nand-flash .
The Common NAND should be able to harbour other kinds of NAND than raw NAND.

I fully understand if you will not want to review the changed code 
again. But maybe you are willing to quickly browse through the 
documentation to see if it looks OK at first glance.
