If I am not mistaken, the DSP has access to all the IO registers, so
you should be able to just use it, check the TRM for the address
mapping...

Vladimir is spot-on.

Just a little remark: If you're working with an OS on the ARM just make
sure that you don't use the SPI from the ARM. E.g. in Linux disable
kernel functionality for SPI. Otherwise all kinds of strange things will
happen.

Here is a response I got from TI when I asked about using DSP side drivers:
