Great to see more USB support for eCos.

I note that you've defined a new eCos target for "STM3210E-EVAL with
USB". This should not be necessary. If you take a look at one of the
other targets with USB support (eg "assabet") there's a CDL option which
controls compilation of the USB hardware driver source code. In the case
of assabet, this is the CYGFUN_DEVS_USB_SA11X0_EP0 option. This option
is controlled by the CYGINT_IO_USB_SLAVE_CLIENTS interface. The
intention is that other packages implement this interface to indicate
that the USB hardware driver is required.
Can you do something similar for your own target to eliminate the need
for an extra target definition in ecos.db? The assabet target is old and
may not offer the best example.
