The overall camera stack architecture shouldn't depend on a particular
platform, but libcamera has SoC-specific support. We do support
Raspberry Pi platforms, but out team has only tested Raspberry Pi 3 and
4. I believe the Raspberry Pi 0 should be supported in theory, but if I
recall correctly the slower ARM core may make it a bit more challenging
in practice.

That being said, enabling libcamera support for the Ambarella SoCs would
be interesting. It would require Ambarella-specific code in libcamera,
which in turns would require kernel drivers to be submitted to the
linux-media mailing list for upstream.
