Subject: [PATCH 0/3] arm64: dts: qcom: qcm6490: Introduce Particle Tachyon

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.
