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: http://wiki.linux-xtensa.org/index.php/Toolchain_Overlay_File -- Thanks. -- Max
