From c839adec884ed601204d527f021bf638e879a61f Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Mon, 15 Aug 2011 17:17:35 +0300 Subject: [PATCH] isa: add isa_address_space() A helper that returns the address space used by ISA devices. Useful for getting rid of isa_mem_base, multiple ISA buses, or ISA buses behind bridges.
