I've implemented the PLATFORM_QUIRK_DOM0_MAP_DISABLED_DEVICE quirk in my
own working tree. It seems to work very well on fixing this issue. +1 
to this idea.

Then I finished new smp initialization callbacks for omap5.

However, the new xen version still has some issues to boot dom0 on OMAP5.

Right now, Dumping cpu0 guest state shows that PC stays at __loop_delay,
while cpu1 stays at cpu_relax() line of ipi_cpu_stop(), using addr2line
to translate PC to the C code location.

Any ideas?
