Ignoring smp_cpus value". 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.
