Probably mcf5249 will be supported in the next week. You can check skyeye developer mail list to get latest update information about SkyEye development.
You can use the following skyeye.conf to simulate 5249
#skyeye config file sample
arch:coldfire
mach:mcf5249
And 5272 simulation can employ the following content:
#skyeye config file sample
arch:coldfire
mach:mcf5272
But 5272 simulation is in development. We will try to finish it in the following week.
