I'm not sure that it isn't quite comparable to porting to a new platform. You've either got to figure out what the thing that usually runs before the kernel does in the way of setup and duplicate that in the kexec code so that a stock kernel will start up correctly, or you've got to modify the kernel startup code to work forward from the configuration in effect at the time kexec under the old kernel hands over to it. You know the kernel should work once the low level startup/handoff is properly accomplished - the work to be done is figuring out that low level part. Which I think is probably a lot like porting. -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
