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 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Rob Herring <robh@kernel.org>
