- we currently don't support 'shipping the topology and firmware
bundled up in a single image to avoid them getting out of sync'. No idea how that might work.
Seems like it'd be trivial to arrange in the kernel, or with userspace firmware loading the loader could do the unpacking.
- if the machine driver is specified in DeviceTree, then the topology
used is *required* to be aligned with the machine driver. The rules are that a topology may not make references to a BE dailink exposed in the machine driver, but conversely if the topology makes a reference to a BE dailink that is not exposed in the machine driver the topology parsing will fail. It's one of the current weaknesses of topology-based solutions, we have non-configurable hardware-related things that are described in topology but should really be described in platform firmware, be it ACPI or DT, and provided to the topology.
That seems like an orthogonal issue here? The requirement for a firmware that's joined up with the hardware (and system description) that it's being used with exists regardless of how we rename things.
