If you don't need to additionally read or write the flash with any non-Linux system, IMHO the way to go is using a standard Linux Flash file system. I some time ago was able to read / write files in the flash of a NEEK dev board by just using what the community distribution provided out of the box. I used JFFS2, but AFAIK, nowadays UBIFS is recommended over JFFS2.
