#ifdef CONFIG_CPU_SHX3 /* * The PMCAT location for SH-X3 CPUs was quietly moved, while the CCBR * and PMCTR locations remains tentatively constant. This change remains * wholly undocumented, and was simply found through trial and error. * * Early cuts of SH-X3 still appear to use the SH-X/SH-X2 locations, and * it's unclear when this ceased to be the case. For now we always use * the new location (if future parts keep up with this trend then * scanning for them at runtime also remains a viable option.) * * The gap in the register space also suggests that there are other * undocumented counters, so this will need to be revisited at a later * point in time.
