This seems a MIPS feature that is not fully mainstreamed, I suppose we 
miss the DSPRAM patches, see:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg638373.html

This code is currently not reachable:

$ git grep saarp
hw/mips/cps.c:98:    saar_present = (bool)env->saarp;
target/mips/cpu.h:1103:    int saarp;
