[En-Nut-Discussion] RFC: License Considerations

[Ulrich Prinz]

For STM32 there is no license issue. I have the agreement from STM that 
we may use their code and keep the STM disclaimer in front of the BSD 
header and put everything under BSD.

That was for the original STM library files. But most of them where 
completely rewritten or optimized in a way that original code is almost 
not existing. So the STM diclaimers have been removed.

The next thing is that the chip manufacturers do not want to limit the 
code in any way of usage, open or closed source. Why should they, thei 
want to sell the chips.
They just do not want to be held responsible for any thing that goes 
wrong with the code. So if you build code for an avionic control board, 
the chip manufacturer is not responsible if the plane crash was caused 
by his software library.
