    usb/gadget: add the fastboot gadget · 3aab70af
    Sebastian Siewior authored
    This patch contains an implementation of the fastboot protocol on the
    device side and documentation. This is based on USB download gadget
    infrastructure. The fastboot function implements the getvar, reboot,
    download and reboot commands. What is missing is the flash handling i.e.
    writting the image to media.
    
    v3 (Rob Herring):
    This is based on http://patchwork.ozlabs.org/patch/126798/ with the
    following changes:
    - Rebase to current mainline and updates for current gadget API
    - Use SPDX identifiers for licenses
    - Traced the history and added missing copyright to cmd_fastboot.c
    - Use load_addr/load_size for transfer buffer
    - Allow vendor strings to be optional
    - Set vendor/product ID from config defines
    - Allow Ctrl-C to exit fastboot mode
    v4:
    - Major re-write to use the USB download gadget. Consolidated function
    code to a single file.
    - Moved globals into single struct.
    - Use puts and putc as appropriate.
    - Added CONFIG_USB_FASTBOOT_BUF_ADDR and CONFIG_USB_FASTBOOT_BUF_SIZE to
    set the fastboot transfer buffer.
    v5:
    - Add CONFIG option documentation to README
    - Rebase using new downloader registration
