The following tables show the offset values for all ROMENTRY values when a v8 memory map is
implemented and the offset values for all ROMENTRY values when a legacy v7 memory map is
implemented.
If a core is not implemented, the ROMENTRY registers for its debug, CTI, PMU, and ETM trace unit
components are 0x00000000 when a v8 memory map is implemented and 0x00000002 when a v7
memory map is implemented.
If a core is implemented but the ETM trace unit is not implemented then the corresponding ROMENTRY
register is 0x00000002 in both the v7 and v8 memory maps.
