	The CSND service talks to the DSP using the DSP FIFO to negotiate what CSND channels are allocated to the DSP, and this seems to be channels 0-7 (usually). The rest are dedicated to CSND services.

	For cache operations addresses must be in 0x14000000-0x1C000000 range. Starting with [[8.0.0-18]] addresses in the range 0x30000000-0x40000000 are also allowed.
