[U-Boot] [PATCH v2 0/4] DFU initial implementation

[Andrzej Pietrasiewicz]

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.

  dfu: protocol initial implementation
  dfu: generic backend parts
  dfu: command implementation
  dfu: target-specific implementation for Goni
