Richard Hughes 87d39d06a3 ccgx: Do not store the silicon ID in the image address 
First, it's a hack; second we actually need to store the start address for
flashing FW2 on asymmetric hardware...

Cypress support

Introduction

This plugin can flash firmware on Cypress CCGx USB-C controller family of devices used in dock solutions.

Supported devices:

  • Lenovo Gen2 Dock
  • Lenovo Hybrid Dock

Firmware Format

The daemon will decompress the cabinet archive and extract several firmware blobs in cyacd file format. See https://community.cypress.com/docs/DOC-10562 for more details.

This plugin supports the following protocol ID:

  • com.cypress.ccgx

GUID Generation

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

  • USB\VID_17EF&PID_A38F

They additionally add one InstanceId which corresponds to the device mode, e.g.

  • USB\VID_17EF&PID_A38F&MODE_BOOT
  • USB\VID_17EF&PID_A38F&MODE_FW1
  • USB\VID_17EF&PID_A38F&MODE_FW2

Vendor ID Security

The vendor ID is set from the USB vendor, for example set to USB:0x17EF
