ESS Maestro1,2 chip family used to consist of two parts WP
and ASSP. ; WP is Wave Processor, ASSP is Application Specific Signal
Processor
netbsd's maestro driver(esm) depend on thats WP, not
supported ASSP.
ESS Maestro3 & Allegro chip family used only ASSP, WP was
eliminated.

official information about ASSP is not available, 
but more information may be here.
