The "mbvanilla-flash.c" file is "hard-wired" to this address and size, which
are both wrong for the board and configuration you and I are using. I
changed them by hand to get up and running and then forgot to say so. (There
was a brief exchange, on the list, between John and me about this about 2
weeks ago.) By the way, I still have not managed to make flatfsd "happy".
That is, counter to John's suspiscion (See previous thread mentioned,
above.), flatfsd still makes the same complaint at every boot regarding not
seeing the right file system and re-creates the FLASH partitions. At least,
it tries; I imagine that, if it were succeeding, it would cease complaining
about not seeing the right file system.

Anyway, here're the diff for that file:
