It is currently work in progress in eCos, but as yet uncommitted (far more
info and history than you need to know is here:
<http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001524>). Most
development is taking place on a Freescale Kinetis board, primarily by
Ilija Kocho, with me interfering along the way ;-). The eCos changes still
need to be reviewed before they're committed.

STM32F4 is likely to follow very soon after. Ironically, it's not likely
to be committed until we have some confidence that what goes into GDB will
match up with what the stub is doing! We wouldn't want to commit something
that has to change in an incompatible way.
