The tomu-bootloader repo is licensed (presumably in its entirety) under GPL3. It's not immediately clear what this means for DFU applications that are made compatible with Toboot with the aid of toboot-api.h. It seems exceedingly unlikely that using a single header with some constant and struct definitions would turn an application into a "modified version" of Toboot in the sense of GPL.
Still, it would be clearer if the API header were licensed more permissively, e.g. with an explicit permission that allowed it to be used for making non-GPL applications compatible with toboot.
