On x86, we require that HVM save records only contain architectural
state.  Not knowing arm myself, it is not clear from your comments
whether this is the case or not.  Can you confirm whether it is or not?
Most states are guest architecture states which include core registers, arch timer, memory. GIC states are arguable, given that Xen uses data structures (e.g. struct vgic_irq_rank) to represent GIC states internally.
