ABSTRACT:
An embodiment of the present invention is a technique to provide resource mapping. A boot target of a platform is analyzed to determine if the boot target supports address mapping of a platform resource above a legacy limit. A new resource mapping beyond an address range of a memory installed on the platform is constructed if the address mapping above the legacy limit is supported. The new resource mapping is within a processor address space of a processor. An access is directed to the platform resource using the new resource mapping.
