Hi Chris,
FYI, xtensa has an error that happen in the below 2 configs:
xtensa-audio_kc705_defconfig (attached as .config)
xtensa-smp_lx200_defconfig
It's too old to be bisect friendly. It'd be great if can be fixed.

I will post patches that add these core variants to xtensa arch.
There's still an issue though: they wouldn't build with the default xtensa
toolchain, because both these configurations have HiFi coprocessor and
there's assembly code in variant-specific files that saves and restores
coprocessor registers. Currently every xtensa core variant requires a
toolchain specifically built for it with corresponding configuration overlay:

Thanks.
