Hi Marc,

Thanks for your reply, i have managed to boot host and guest on foundation model.

Enabling vexpress platform from menuconfig was missing part from my side.

Thanks,

Pranav

Hmmm...

root@hot-poop:~# dmesg | head
Initializing cgroup subsys cpu
Linux version 3.8.0-rc4+ (maz@e102391-lin) (gcc version 4.7.1 (0.11.114) ) #761 SMP PREEMPT Wed Jan 23 11:43:41 GMT 2013

^^^^^^^^^^^^^^^^^^^^^^^

Seems to be booting well enough for me. Are you sure you used the supplied DT
(as mentioned in the below email)?

There is no need for a platforms directory any more. The vexpress support is
now just a configuration option.
