STM32F4 BSP usage

Ok.  I didn't want to re-invent the wheel.  The libraries provided by ST are probably not usable due to the licensing restrictions.  

Would it be acceptable to not include the ST libraries in RTEMS but require the end-user of the BSP to acquire them?  There are many examples of how to configure the STM32 hardware but these examples assume the ST libraries are being used.  Simply re-creating the libraries might not be possible without using the source code of the libraries since the source code is the only documentation in most cases.
