Yes, DSPGW can't be used as is unless you have ARM9/11 and DSPC55x
combination as in case of OMAP1/OMAP2 series (except OMAP730 I
believe). But as you said it has ARM7 on the other side having
interface like mailbox and shared memory to talk with ARM9. In this
case you can develop similar interface like in current DSPGW (and most
of the code can be re-used). Think of IVA1.0 in OMAP2420. It is ARM7
with bunch of co-processor having their own SRAM's.
