This is dead code. It's based on the cAVS "IPC" mechanism to allow communication to and from the host CPU. But there is no test rig in the Zephyr tree for the protocol defined. And in fact the only Zephyr-based user of the IPC mechanism (Sound Open Firmware) has its own IPC driver and speaks its own protocol with the host kernel. That driver needs to migrate into Zephyr soon and this legacy bit is just confusing. Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
