Save/restore and migration

PCI device assignment to DomUs

Expose Wallclock time to guests
Contact: xen-devel@lists.xen.org
Description: Current Xen on ARM does not popular the wallclock time fields of the shared info with anything useful. It should do so...
References: Partial/incomplete code http://article.gmane.org/gmane.comp.emulators.xen.devel/220265

More flexible early printk support
Contact: xen-devel@lists.xen.org
Description: Allow a single Xen binary to support multiple platforms for early_printk Rather than parsing the DTB early in asm to get the command line it would probably be sufficient to have a magic hex byte at a specific offset which could be edited by a simple tool.
