This is a special debug version of leo2moko intended for use by FreeCalypso
developers only; it does not provide any additional features for Freerunner
users beyond standard leo2moko-r1 aka moko12; non-developer users are advised
to stay with the just-mentioned stable release.

The primary intended use of this debug fw version is to enable FreeCalypso
developers to troubleshoot misbehavior in our current gcc-built fw version
by comparing the operation of the fw against a known working reference;
the debug features added in this version are:

* Same AT-over-RVTMUX mechanism as implemented in FreeCalypso mainline;

* ETM FFS access protocol changed from TMFFS1 (used by some TI Windows tools,
  apparently) to TMFFS2 (the version adopted for FreeCalypso) to allow the
  flash file system to be manipulated with fc-fsio while this fw is running.
