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

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:
