Right now, we have no modules which are enabled. We will have a bootable Linux
integrating the Xen code, but
without starting the hypervisor.
I propose that you wait a couple of days while we're solving the last issues so
that you will be able to help us in enabling step-by-step the different
functions.
Patrick, on the other hand, is getting the bootstrap code from Samsung (xen-arm
project) into an original XEN tree (3.1) on i.MX21, before going forward to the
i.MX31.

Enabling the functions will consist in un-commenting each function call in the
main setup function provided that the memory has been correctly configured.
Again, Samsung's port will be essential for this part.
