The ARM target doesn't implement ARM7TDMI. The oldest CPU we support
is the ARM9. (I suppose ARM7TDMI could in theory be added; we have
other v4T architecture cores already. Personally I'm more interested
in the newer end of ARM's product line than the older end, though...)

QEMU doesn't support this -- it emulates an entire system, it does not
provide a pluggable component you can use to do only "cpu emulation"
as part of some other system emulator.

We also don't support having multiple CPUs with different architectures
in one emulator: you can have an ARM emulator, or an SH4 emulator,
but not an emulation of a system with both an ARM and an SH4 core.
