This is the license the "design support" tab of the link you provided 
above (
points to.

At the very bottom of the tab mentioned above, under "Firmware" you find 
a dedicated STM32F4-Discovery Firmware zip package, which, when you 
unpackage it contains a SW license.

To me, this SW license disqualifies any piece of SW from the 
"STM32F4-Discovery Firmware" package from inclusion into RTEMS.

Well, it depends on whose files the files are derived from.

The license Dimitry mentioned in another mail, would seem fine to me at 
first glance.
