Support for LTE/Modem
While the combined WiFi/modem firmware is already loaded properly and WiFi works, LTE at the very least needs testing as I have yet been unable to do so. It may work, but more likely it will not. It seems that some files needed by the remote processor are only loaded with some modifications to tqftpserv, which also complains about the seek operation being unsupported.
FYI, it looks like the modem actually works. I can see it with qmicli by specifying the -d qrtr://0 parameter (IIRC).
ModemManager still doesn't see the device, but maybe this is just because the version shipped with Arch Linux doesn't (yet?) support QMI.
You can see a list of other devices by running qrtr-lookup. GPS (#39) is probably also supported if we use qmi-gps-proxy (for example as seen here).
I'll update this thread as soon as I discover more.

Despite this, ModemManager doesn't seem to find the modem (and there is no /dev/cdc-wwan device either):
$ mmcli -L
No modems were found
The logs mention the device, but it looks like it fails to initialize it (couldn't create modem for device 'qcom-soc': Failed to find a net port in the QMI modem):
