Google WiFi (codename: Gale) is an IPQ4019-based AP, with 2 Ethernet ports, 2x2 2.4+5GHz WiFi, 512 MB RAM, 4 GB eMMC, and a USB type C port. In its stock configuration, it runs a Chromium OS-based system, but you wouldn't know it, since you can only manage it via a "cloud" + mobile-app system.
The "v2" label is coded into the bootloader, which prefers the "google,gale-v2" compatible string. I believe "v1" must have been pre-release hardware. Note: this is *not* the Google Nest WiFi, released in 2019. I include "factory.bin" support, where we generate a GPT-based disk image with 2 partitions -- a kernel partition (using the custom "Chrome OS kernel" GUID type) and a root filesystem partition. If the AP is in Developer Mode, the stock bootloader can boot it via a USB disk or (after gaining access via USB boot) flashed to the eMMC. Sysupgrade also seems to work OK, although I've omitted some of the (re)partitioning handling. I also hard-code /dev/mmcblk0 -- while MMC device numbering can technically change, there's no other MMC controller present (e.g., no SD card slot). "FEATURES=boot-part rootfs-part" is required to get kernel and rootfs partition sizes established. This adds extra (unused) configuration parameters for other ipq40xx targets, so I'm not sure if this is the "right" thing to do either. Features I have tested: * Ethernet, both WAN and LAN ports * eMMC * USB-C (hub, power-delivery, peripherals) * LED0 (R/G/B) * WiFi (limited testing) * SPI flash * Serial console: once in developer mode, console can be accessed via the USB-C port with SuzyQable, or other similar "Closed Case Debugging" tools: https://chromium.googlesource.com/chromiumos/third_party/hdctools/+/master/docs/ccd.md#suzyq-suzyqable Not tested: * TPM * LED1, LED2: I'm not even confident they are actually populated anywhere Known not working: * Reboot: this seems to require some additional TrustZone / SCM configuration; with additional local patches, I have this working, but I'm still trying to figure out exactly the right way I should integrate this. Ideally, I could propose it upstream, instead of just adding a custom OpenWRT patch. Without this patch, reboot just hangs the system. (NB: I've found at least one other user report of this on an "IPQ4019" device, but I don't know yet if that's the same.) * There's a single external button, and a few useful internal GPIO switches. I haven't hooked them up. Much of the DTS is pulled from the Chrome OS kernel 3.18 branch, which the manufacturer image uses. Note: the manufacturer bootloader knows how to patch in calibration data via the wifi{0,1} aliases in the DTB, so while these properties aren't present in the DTS, they are available at runtime: # ls -l /sys/firmware/devicetree/base/soc/wifi@a*/qcom,ath10k-pre-calibration-data -r--r--r-- 1 root root 12064 Jul 15 19:11 /sys/firmware/devicetree/base/soc/wifi@a000000/qcom,ath10k-pre-calibration-data -r--r--r-- 1 root root 12064 Jul 15 19:11 /sys/firmware/devicetree/base/soc/wifi@a800000/qcom,ath10k-pre-calibration-data Ethernet MAC addresses are similarly patched in via the ethernet{0,1} aliases.
