UFFS looks like a good fit for eCos. However, it is licensed under the
LGPL. I wonder if the authors would be willing to license the filesystem
under the eCos public license (dual license) and make a copyright
assignment to the FSF. Is this something you have discussed with them?
Our current policies do not allow us to accept LPGL run-time code into
the eCos repository.
I assume that your port would sit under the standard eCos Flash I/O
layer (CYGPKG_IO_FLASH). As with all imported packages, it would also be
* Minimise changes to the imported source code so it is as easy as
possible to keep the eCos port up to date.
* Provide all the configurability offered within the imported code as
eCos CDL options.
