From: Matheus Tavares Bernardino <quic_mathbern@quicinc.com>
Currently, qemu-hexagon only models the v67 cpu. Nonetheless if we try
to get this information with `-cpu help`, qemu just exists with an error
code and no output. Let's correct that.
The code is basically a copy from target/alpha/cpu.h, but we strip the
"-hexagon-cpu" suffix before printing. This is to avoid confusing
situations like the following:
$ qemu-hexagon -cpu help
Available CPUs:
v67-hexagon-cpu
$ qemu-hexagon -cpu v67-hexagon-cpu ./prog
qemu-hexagon: unable to find CPU model 'v67-hexagon-cpu'
