Hi,

At Purism we use the Nitrokey Pro as the basis for our own key called Librem Key. We're submitting the Librem Key for Respects Your Freedom certification. In discussions with the certification folks they note that there's some ambiguity regarding the headers in the files in the nitrokey-pro-firmware/build/gcc directory.

The files STM32_COMMON.ld & STM32_SEC_FLASH.ld have a header which says;

/*
Common part of the linker scripts for STR71x devices in FLASH mode
(that is, the FLASH is seen at 0)
Copyright RAISONANCE 2005
You can use, modify and distribute thisfile freely, but without any waranty.
*/

while STM32_128K_20K_FLASH.ld and stm32.ld have header that say;

/*
Linker script for STM32F10x
Copyright RAISONANCE 2007 (modified by Lanchon 1-Feb-2008)
You can use, copy and distribute this file freely, but without any waranty.
Configure memory sizes, end of stack and boot mode for your project here.
*/

The issues are;
-- The word "warranty" is spelled "waranty".
-- Not all the files explicitly grant the right to modify.
-- Not all the files explicitly grant the right to copy.

I'd like to propose a PR which I hope might fix this and be suitable for your needs. Alternatively, those files can be fixed by whomever wrote them if they still hold the copyright and have not contributed them into the public domain.
