This means the CONFIG_CS_DSP symbol is not in the namespace of Kconfig and never gets selected. We just discussed this problem on IRC the other day as I had the same issue. I think we should move all the "source" statements for driver Kconfig files from architecture specific inclusions to drivers/Kconfig. Arnd
