+
+ * sim-main.h (m68hc11_map_level): Define level of address mappings.
+ * dv-m68hc11eepr.c (struct m68hc11eepr ): New flag to indicate
+ whether the eeprom is currently mapped or not.
+ (m68hc11eepr_port_event): Use the flag to see if we must unmap
+ or map the eeprom. Update the flag to reflect the current state.
+ Use M6811_EEPROM_LEVEL when mapping the eeprom.
+ (m68hc11eepr_finish): Remove overlap hack.
+ (attach_m68hc11eepr_regs): Use M6811_IO_LEVEL when mapping the
+ config and control registers.
+ * dv-m68hc11.c (m68hc11cpu_finish): Remove overlap hack.
+ (attach_m68hc11_regs): Use M6811_IO_LEVEL.
+ (m68hc11cpu_io_write): Likewise when unmapping and re-mapping.
+ * dv-m68hc11spi.c (m68hc11spi_finish): Likewise.
