Currentlly, we use Synopsys DesignWare DMA Controller for baytrail/haswell/broadwell ADSP firmware loading, but for skylake, we don't use it, compiling sst-firmware.c may introduce error when CONFIG_DW_DMAC_CORE is not enabled: sound/built-in.o: In function `sst_dma_new': (.text+0xd7b38): undefined reference to `dw_dma_probe' sound/built-in.o: In function `sst_dma_free': (.text+0xd7c0a): undefined reference to `dw_dma_remove' Here we only compile sst-firmware when CONFIG_DW_DMAC_CORE is selected, to fix the linking error issue.
