The iMX lpuart driver added at 44e17aa60d47 ("xen/arm: Add i.MX lpuart driver")
is not enough to boot a Linux based dom0 when certain drivers, such as the
watchdog driver, are enabled.
We're also fixing compatibles in imx-lpuart to allow Xen to use the UART
on the QXP variant as well.
When it comes to the watchdog we're currently only implementing the support
for letting Dom0 manage it. There is also a desire for another approach
where Xen kicks the watchdog (dom0-less use-cases etc). This approach is
not covered by this patch set.
