That's just a warning and can be suppressed with -smp 2.
Not sure what problem you're running into, but in general the rule of
thumb is that if want to emulate an Odroid U2 you'll need to write a
machine emulation file (reusing the relevant parts of exynos4210 code),
or if you want to emulate an SMDKC210 you'll need U-Boot/fdt/kernel for
that board even if it uses a similar SoC.
As for taking U-Boot out of the equation, you can use -kernel and
-initrd options directly. You neither mentioned your version nor your
command line btw.
