Dear All,
This is a quick-and-dirty proof-of-concept for splitting the dfu into core dfu gadget, generic parts of dfu backend, dfu command and target-specific implementation for Goni.
This patch definitely needs some coding style cleanups.
Also, the place for storing generic parts of dfu was chosen somewhat arbitrary and can be changed if a better alternative is found.
The original idea of the flash_entity was to equip it with a void * to a context structure, which is not interpreted by the dfu gadget but passed to the dfu backend and understood there. I am still hesitating if flash_entity_ctx is generic enough to be generalized, as of now I assumed it is. If it wasn't then less common code could be extracted.
@Stefan: you need the first 3 patches from this series, and then you need to implement your own target-specific parts. In fact, all is expected from the target, is to provide board_dfu_init/cleanup pair and call register_flash_entities.
