[isar-cip-core][PATCH 0/2] swupdate-config-wfx: make device identity configurable

[Alperen Erdogan]

Add WFX_DEVICE_ID variable to allow configuring the wfx suricatta
device identity at build time. Defaults to $(cat /etc/machine-id).

Looks good to me so far - but would you mind explaining your use case as
well? Do you replace the extraction logic because your target provides
an production device ID differently, or do you pin it to fixed known
value in a development image?

for this use case, target uses a unique device ID provided by the internal system, so it’s read from a different file path.
