The Particle Tachyon is a single board computer with 5G connectivity
with AI accelerator, based on the Qualcomm QCM6490 platform.
Introduce the board, with support for UFS, USB, USB Type-C PD and
altmode (DisplayPort), GPU, charger/battery status, PCIe shield,
SD-card, and remoteprocs.

Is 2 lanes a hw limitation?

I believe I saw the same problem on Rb3Gen2. Do we know if there's any

The should be qcm6490, not qcom6490...
Same with a couple of the other firmware paths as well.
