Remind me why we're using start_info instead of properties in the Open
Firmware device tree?
point, counter point (SI == why start_info, OF == why not all OF
devtree)
SI: start_info contains members that could have their values
changed before the kernel is "restored"
from either a checkpoint or a migration.
OF: since we source this information from "within" the domain
(console_mfn, store_mfn, etc) we do not
expect most if not all of them to change.
SI: There are about 30 references to this structure in drivers/xen
OF: we could build start_info in the kernel from devtree
information rather then build it in libxc and map it.
SI: Not sure we are ready to invent _everything_ until it is all
fully understood
OF: scardy-cat!
SI: we really do not have a dynamic devtree for DomU
OF: that is until Hollis finishes the code that provides one.
