This is a bit painful PR to review, is there a reason to lump so much stuff in one PR? There are mechanical move of toml data, new fancy cmake logic, important bugfixes, and who knows what in the series. I did go through it and looks fine to merge, so please, simpler PRs when possible.

Why here as well, shouldn't the definition in board conf file be enough?

@kv2019i yes, thanks, I noticed that already too, will fix in the next version

This fix would warrant a separate PR for example.

Build src as a loadable llext module. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
To make volume an LLEXT module it should have a single TOML configuration file named volume.toml. This is easy to do, using respective Kconfig options. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
When building volume as an LLEXT module, two more symbols are required: __divdi3() and module_set_configuration(), export them. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
This makes it possible to build volume as an LLEXT module to be loaded at run-time. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
When built as an llext module, eq_fir requires several base-firmware provided symbols, export them. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
Add support for LLEXT building to eq-fir. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>

Btw, any reason why this is not mart of the src makefile ?

@lgirdwood which one? If you mean https://github.com/thesofproject/sof/blob/main/src/audio/src/CMakeLists.txt then it isn't used in Zephyr builds, (most) audio sources are still built from https://github.com/thesofproject/sof/blob/main/zephyr/CMakeLists.txt Once we change that to use per-component cmake scripts, then yes, I think it should be possible to keep both monolithic and modular instructions in the same file. But I'd have to try to know for sure

ok, so we need to circle back to this later when ready.

Why remove this? Seems like a no-op now (given current default), but seems out of place in this commit.

@kv2019i yeah, well, it's all SRC... But if you don't want it there, can drop. It just makes it better prepared for an eventual default-M transition
