End users writing applications that use the HPI interface do not have to use any of the below defines; they are only necessary for building drivers

HPI_DSPCODE_FILE: DSP code is supplied as a file that is opened and read from by the driver.

HPI_DSPCODE_FIRMWARE: DSP code is read using the hotplug firmware loader module. Only valid when compiling the HPI kernel driver under Linux.
