There are none at present. I have plans to do a VFAT filesystem at
some point, but writing a filesystem is not a trivial job and it's
difficult to find the time.

All Linux filesystems are strongly dependent on the Linux kernel
environment: inodes, buffer cache, device drivers, synchronization
etc. To port them we would have to effectively reimplement the Linux
kernel in eCos. The same is true of any BSD-derived filesystems.
But the licensing issue effectively prevents any Linux code being
imported into eCos.
