Thank you for implementing this. Good idea. There is however a small
glitch introduced with this patch - both the r2d and the shix board
can pass "any" as cpu string when calling cpu_init(). This results in
a "Unable to find CPU definition" error unless the cpu type is
specified on the command line using the -cpu option. Maybe a better
solution would be to pass "SH7751R" from r2d and "SH7750" from shix by
default?
