PMCG nodes were added by IORT revision C, with the unfortunate oversight that it only defined a single base address, and thus was incapable of properly describing PMCG implementations with PMCG_CFGR.RELOC_CTRS = 1, where the counters are in a separate page from the control registers. Revision D corrects this by clarifying the existing field as the page 0 base address and adding a second field to describe the page 1 address when implemented. With the spec now fit for purpose, let's support it. Signed-off-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Rafael J.
