Rename floppy_type macros to make them more consistent with the scsi_type macros, which are named after classes of models with similar memory maps. The MAC_FLOPPY_OLD symbol is introduced to change the relevant base address from 0x50F00000 to 0x50000000 (consistent with MAC_SCSI_OLD). The documentation for LC-class machines has the IO devices at offsets from $50F00000. Use these addresses for MAC_FLOPPY_LC (consistent with MAC_SCSI_LC) because they may not be aliased elsewhere in the memory map. Add comments with controller type information from 'Designing Cards and Drivers for the Macintosh Family', relevant Developer Notes and http://mess.redump.net/mess/driver_info/mac_technical_notes Adopt phys_addr_t to avoid type casts.
