Yes, I have applied publicly available dc232b overlay. Although the
code that returns zeros for privileged SRs is not overlay-specific.

It is not a processor, it is qemu-based ISS that I've been developing.
It emulates dc232b.
I was mostly interested in $ccount/$ccompare.
I started to dig here because although I've implemented access to
these registers in gdbstub, I couldn't make gdb to query them.
