Introduce the Particle Tachyon board (https://www.particle.io/tachyon/),
a single board compute with 5G connectivity and AI accelerator.
The boards currently ships with the Android Boot Loader, but replacing
this with abl2esp allows writing a EFI System Parition and OS partitions
to all of LUN0, and a more UEFI boot experience. A prebuilt version of
abl2esp is provided at [1], as abl2esp-v6.elf.
With a (very) recent version of QDL, a flash programmer from a Tachyon
software release, and a full distro image, this can be achieved with:
qdl prog_firehose_ddr.elf write abl_a abl2esp-v6.elf write abl_b abl2esp-v6.elf write 0 image.raw
The following firmware files are currently used, on top of what's in
linux-firmware already:
qcom/qcm6490/particle/tachyon/a660_zap.mbn
qcom/qcm6490/particle/tachyon/adsp.mbn
qcom/qcm6490/particle/tachyon/cdsp.mbn
qcom/qcm6490/particle/tachyon/ipa_fws.mbn
qcom/qcm6490/particle/tachyon/modem.mbn
In addition to bug fixes that has landed in v6.17-rc this depends on
[2], which is available in linux-next.

Changes in v2:
- Fixed qcm6490 vs qcom6490 in a couple firmware-name paths
- Reordered once pinctrl-0 vs pinctrl-names
- Provided speed property for i2c1 to avoid Linux informing us about
picking 100kHz (no value in downstream)
- Drop a of_graph connections and properties that was already
established in dtsi
- Link to v1: https://lore.kernel.org/r/20250910-tachyon-v1-0-5090bfd133e0@oss.qualcomm.com
