I'll add
* Different Core ARCH
* FDT or similar to describe I/O (MEM, PCI, GPIO) acessible for
each instance
* Mailbox Architecture
* boot preocedure (bootloader as example done by Kumar Gala
for the mpc8572ds in linux & U-Boot)
* sharing rootfs (RO) (reduce the rootfs size on embedded)
Best Regards,
J.
