There are a few issues with the code as it stands, which are being worked
on right now hopefully in time for eCos 2.0. There are bugs in readdir and
the garbage collector at least, off the top of my head, but this is still
being played with.

JFFS2 is host endian only. (This may well change at some point).

Do you know you need to modify your flash driver to support unaligned
writes? And depending on how you write your code, that may be endian
specific!
