[BUG] Reduce footprint by putting large items under kconfig options

[lgirdwood]

Describe the bug
Improve footprint by making more data and text items optional under kconfig. Platforms with limited memories must have a smaller set of features (e.g. less SRC conversion ratios, less module, less debug etc) compared to recent platforms with larger memories.

To Reproduce

for i in $( find build_*/sof ); do
	echo $i
	xtensa-apl-elf-nm -S --size-sort --reverse-sort $i | head -n 20
	echo
done

Low hanging fruit is

• SRC coefficients.
• Trig tables.
• primary core
• Heap tables.

Yep. I can do the first two items: SRC and sine lookup tables.

[lgirdwood]

@slawblauciak any comments on primary_core_data ?

[slawblauciak]

@lgirdwood not sure, not exactly familiar with the static data FW embeds in the binary.

[lgirdwood]

@slawblauciak thanks, it may need some Kconfig #idefs around some it's data members as it seems odd that on UP platforms it's 12k and on SMP platforms it's 8k ?

[slawblauciak]

@lgirdwood I'll ask around. Somebody who worked on SMP code might know.

[mmaka1]

@lgirdwood @slawblauciak primary_core_data size is not related to UP vs. SMP, it is just coincidence. The size is determined by number of interrupt levels selected in the platform configuration, as each context uses dedicated 4K stack.

[lgirdwood]

@mmaka1 thanks got you. So these are already optimised.

[lgirdwood]

@singalsu @johnylin76 @ShriramShastry @aiChaoSONG fyi - any chance we can move more of these under kconfig for v1.7 ?

[singalsu]

Yes, I'll do the SRC coefficients and trig tables kconfig. For SRC I think the tiny conversions set (as for generic C) with only 16/32/44.1/48 but with the better quality used today should be a good default. So far there has been no need for the near full MPEG-AAC rates conversions matrix.

[lgirdwood]

@singalsu thanks.
