Richard Hughes 52441f28a4 Allow objects to deserialize to XML 
This makes a lot more sense; we can parse a firmware and export the same XML
we would use in a .builder.xml file. This allows us to two two things:

 * Check we can round trip from XML -> binary -> XML

 * Using a .builder.xml file we can check ->write() is endian safe

Fresco PD Support

Introduction

This plugin is used to update Power Devlivery devices by Fresco.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecifed binary format.

This plugin supports the following protocol ID:

  • com.frescologic.pd

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_1D5C&PID_7102&REV_0001
  • USB\VID_1D5C&PID_7102
  • USB\VID_1D5C

These devices also use custom GUID values, e.g.

  • USB\VID_1D5C&PID_7102&CID_01

Update Behavior

The firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x1D5C

External interface access

This plugin requires read/write access to /dev/bus/usb.
