Hi Lei,
I'm copying Andy Doan directly on this, since he's had more experience of
getting FM working in LAVA and can probably point you in the right direction.

Hi all,
this patch series implements Xen support for ARMv7 with virtualization
extensions. It allows a Linux guest to boot as dom0 and
as domU on Xen on ARM. PV console, disk and network frontends and
backends are all working correctly.
It has been tested on a Versatile Express Cortex A15 emulato
Add a doc to describe the Xen ARM device tree bindings
Changes in v5:
- add a comment about the size of the grant table memory region;
- add a comment about the required presence of a GIC node;
- specify that the described properties are part of a top-level
"hypervisor" node;
- specify #address-
Changes in v2:
- return -ENOSYS rather than -1.

We need them because _set_bit etc are not SMP safe if !CONFIG_SMP. But

Use r12 to pass the hypercall number to the hypervisor.
We need a register to pass the hypercall number because we might not
know it at compile time and HVC only takes an immediate argument.
Among the available registers r12 seems to be the best choice because it

All the original Xen headers have xen_ulong_t as unsigned long type, however
when they have been imported in Linux, xen_ulong_t has been replaced with
unsigned long. That might work for x86 and ia64 but it does not for arm.
Bring back xen_ulong_t and let each architecture define xen_ulong_t as they
