Sorry, you're on your own here.

Once Linux is running, RedBoot is out of the picture (i.e. no longer
usable), so you'd need to duplicate the functionality that's used by
RedBoot to handle the 'fconfig' data.  All of the details of what this
entails can be found by reading
  .../ecos/packages/redboot/current/src/fconfig.c

In Linux, you could use MTD to access the 'fconfig' data.

n.b. I've thought about writing these functions (for years), but
haven't found the time.
