(MESS) bw2: Fixed memory mapping. (nw)
(MESS) msm6255: Refactored to use device_memory_interface. (nw)
(MESS) floppy: Added macros for declaring modern floppy formats. The generic floppy formats (D88/DFI/IMD/IPF/MFI/MFM) are now automatically supported in each driver using the modern floppy code. [Curt Coder]
device_memory_interface::space() assert against NULL and
return a reference, and pushed references throughout all
address space usage in the system. Added a has_space()
method to check for those rare case when it is ambiguous.
[Aaron Giles]
Also reinstated the generic space and added fatal error
handlers if anyone tries to actually read/write from it.
device_execute/memory_interfaces respectively in order
to catch unnecessary usage of the corresponding device_t
methods. Removed all existing redundant usage.
