Richard Hughes 1981c63d58 Remove FuFirmwareImage and just use FuFirmware instead 
This allows us to 'nest' firmware formats, and removes a ton of duplication.

The aim here is to deprecate FuFirmwareImage -- it's almost always acting
as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow
custom types. If I'm struggling to work out what should be a FuFirmware and
what should be a FuFirmwareImage then a plugin author has no hope.

For simple payloads we were adding bytes into an image and then the image into
a firmware. This gets really messy when most plugins are treating the FuFirmware
*as* the binary firmware file.

The GBytes saved in the FuFirmware would be considered the payload with the
aim of not using FuFirmwareImage in the single-image case.

Wacom RAW Support

Introduction

This plugin updates integrated Wacom AES and EMR devices. They are typically connected using I²C and not USB.

GUID Generation

The HID DeviceInstanceId values are used, e.g. HIDRAW\VEN_056A&DEV_4875.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in Intel HEX file format.

This plugin supports the following protocol ID:

  • com.wacom.raw

Quirk use

This plugin uses the following plugin-specific quirks:

Quirk Description Minimum fwupd version
WacomI2cFlashBlockSize Block size to transfer firmware 1.2.4
WacomI2cFlashBaseAddr Base address for firmware 1.2.4
WacomI2cFlashSize Maximum size of the firmware zone 1.2.4

Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with a different HIDRAW PID in a bootloader mode. On attach the device re-enumerates back to the runtime mode.

For this reason the REPLUG_MATCH_GUID internal device flag is used so that the bootloader and runtime modes are treated as the same device.

Vendor ID Security

The vendor ID is set from the udev vendor, in this instance set to HIDRAW:0x056A

External interface access

This plugin requires ioctl HIDIOCSFEATURE access.
