Thunderbolt has a new kernel interface starting from version 4.13,
which simplifies updating the host controller and devices: the
kernel now exposes a sysfs interface for the non-volatile memory
as a device node. This can be used to write the new firmware blob.
Updates are then triggered also via a simple write to a sysfs
file (nvm_authenticate), which in turn is also used for error
reporting.
The plugin should be functionally, but a few items are missing:
- image verification
- safe mode handling
* thunderbolt: Add special handling for safe mode on Dell systems
Dell systems are known to have the Model ID the same as the SystemID
that can be recovered from libsmbios. If the thunderbolt controller
is in safe mode, identify with this ID to allow the controller to be
flashed with a good FW.
* Minor changes in Thunderbolt README file
* Remove PCI-oriented GUID
* Handle Thunderbolt controller in safe-mode
* Get progress status updates for Thunderbolt
* Fix for Thunderbolt FW version display
* Style changes from pull request review
