+Functions for reading DSP code to load into DSP
+
+ hpi_dspcode_defines HPI DSP code loading method
+Define exactly one of these to select how the DSP code is supplied to
+the adapter.
+
+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.
