Connected SMIOC DMA to 68k
* SMIOC now reading bytes for serial from the 68k memory space successfully.

68k now running in lockstep with SMIOC for serial
* 68k now uses actual SMIOC as source of SMIOC status, so it waits for the SMIOC to complete commands before continuing.
* SMIOC DMA controllers now being asked to move bytes around
* "write character" (4100) commands to SMIOC are now completing and resulting in correct status being written and sent back to the 68k
* Every now and then the SMIOC stalls for a bit, it seems to be due to spending some time trying to communicate with the 8051 CPU (used to communicate with another cpu on the serial breakout box) that is not currently present in the emulated device.
Next Steps:
* We're going to move the terminal from the r9751 into the SMIOC, and hook it up to the DMA controllers as a hacky temporary solution.
* We need to emulate the 5xxxx memory range in SMIOC to proxy data to/from the 68k memory
* Then we'll start work on emulating the octal uart properly and hooking it up to RS232 channels.

Tinkering to get SMIOC further along
1) Enable 188 cpu to advance DMA immediatley if DRQ is held high when source synchronous DMA is started (It's not clear whether the DMA actually works this way yet)
2) Retrigger the DMA DRQ when a memory access is made to the DMA window (future work needed to proxy the reads/writes to the 68k's main memory) This is needed to support multibyte DMA reads/writes to the 68k window.
3) Reverse the bytes in the status register (based on current incomplete understanding of how this is encoded)
4) Connect the status register back to the r9751 on SMIOC status read
Current state: SMIOC's main board DMA state machine now completes the DMA transfer from the main board (With incorrect data), but we are still getting stuck.
Next steps: SMIOC is now hanging waiting on DMA to UART to complete, we need to implement some emulation of the UART and its connections to the surrounding 16 dma channels in order to make progress.

Experimenting with SMIOC emulation
* Partial fixes for line state issues with persistent line values
When the AM9517 DMA controller mode is updated to change the polarity of DACK/DREQ, it doesn't update the DACK line values / request values (respectively).
This fixes this issue for one of the emulated devices in the file, but the other device has the same problem.
* Add skeleton of SCC2698B UART device
* Early progress on emulating SCC2698B Octal UART
Core structure for IO lines and writing registers is in place.

* Resolved code issues related to upstream changes
* Working around an apparent problem with callbacks on sub-device devices
* Terminal added for serial port attached to SCC2698B UART.
* Things compile and seem to work.
* SMIOC: Serial is now outputting correctly through emulated SMIOC
Some glitches to work out, but this is nearly ready.
* AM9517a should not forget about input line status on master reset.

* Revised tracing in SMIOC and SCC2698B
* Improved tracing approach in r9751

* [R9751] Update drivers to new code patterns after rebase
Rebased on latest mame, Fixed a few issues and updated the callback code patterns based on recent changes in devcb
* [R9751] Improve logging, fix interrupt race
Serial no longer drops output characters
* [R9751] Working on SMIOC emulation
Improved SMIOC emulation accuracy, Made some progress in getting through the disktool initialization sequence, but we are still hitting a problem - It looks like disktool should be resetting the SMIOC board when it starts, but the mechanism for this has not been found.
* [R9751] Improve tracing for system board registers
* [R9751] Improve SMIOC emulation
Still having some trouble with SMIOC but this seems to be an improvement.
SMIOC is now waiting for a status to be read before applying a new status, and mandatory parameter read logic is in place.
* [R9751] Incremental emulation improvements
the SMIOC failure was understood and fixed, and a new approach to getting the hardware to bootstrap correctly was implemented - Still having some problems with it though.
* [R9751] Fixed emulation issues
* Disktool now boots to the console
* UART receive only partly working, I don't think it's fully connected yet.
* [R9751] Further progress on SMIOC emulation
* Figured out the missing command parameter interface to the SMIOC board
* Still blocked because the SMIOC interface to the breakout board through an onboard 8051 is not emulated and the disktool software depends on properties coming from it.
* [R9751] Terminal is fully working for disktool
* Improved the emulation of the 80188 to 451 connection in order to reliably set a status bit disktool depends on.
* [R9751] Fix build after rebase
* [R9751] Cleanup, tracing improvements
* Remove second emulated terminal - SMIOC is now stable enough to run the terminal.
* Remove older and unnecessary emulation/tracing code
* r9751: Fix compile error and modify copyright holders
Zilog Z8038 FIO (FIFO Input/Output Interface Unit). Used to drive the parallel/printer port on the MIPS Rx2030. Passes basic diagnostic tests, but further work depends on progress in the mips.cpp driver.
A skeleton for the Microsoft Jazz architecture, which was implemented in the MIPS Magnum 4000, Olivetti M700-10 and was the base/origin of several other MIPS ARC systems.
* added skeleton Inmos G300/G332/G364 device
* added skeleton NatSemi DP83932C SONIC device

* hp9k_3xx: add HP9122C floppy
Remove HP9895 from the default configuration. 3.5" where
standard on /300 and there's almost no software on it available.
If a user really needs 8" floppy drives on /300, he can do that via
commandline.

* add Intel i8291a GPIB Talker/Listener
Required for the HP 9122C floppy, and used in many other devices.
Basic functionality was implemented to make the HP 9122C work, a few
things are still missing and will be added later. Most of the missing
things where simply not used in the HP9122C so i cannot test them.

* Add HP 9122C floppy drive
These drives where common on HP9000/300 workstations. With the current
implementation TD0's from hpmuseum can be used to boot, and initializing,
reading and writing discs in HP basic works. Tested both high and double
density media. Supported Media formats are TD0 and MFI.

* proposal: move z80daisy* to devices/machine
Seems to me this is a machine, not a CPU? Main reason was to stop the Z80 CPU from being dragged into systems that don't have one just because they use a Z80 family peripheral.
* missed this one (nw)
* missed a spot (nw)
- Use device_resolve_objects to resolve callbacks in output_latch_device (nw)
Note that this renaming is not just for human convenience; genie seems to get confused by modifications to a header called latch.h and decides to recompile everything involving gen_latch.h as well.
Implementation of 28F010 and family flash memory devices. These are not compatible with the JEDEC-standard flash command protocol implemented in intelfsh.
* Don't use device_serial_interface for transmit - it can't support sync modes, on-the-fly register updates, and other weirdness.
* Better modelling of 1-deep transmit queue.
* Better RTS/CTS behaviour.
* Completely overhauled interrupt logic - vectors should be correct for most async modes.
* Implemented different auto-reset receive errors in MPSC vs SIO.
* Implemented SDLC transmission including bit stuffing, transmit CRC, abort, and underrun/end-of-message behaviour.
Added an SDLC consumer device that logs SNA frame headers and data.
The analogue joystick is now emulated. Also fixed a few minor issues
with the memory map.
This also adds a generic Z80 dasisy chain device, for use in drivers
with non-Z80 peripherals.
These humble 16-pin logic devices were commonly used in 8-bit arcade games to control coin counters/lockouts, IRQ flipflops, graphics banking, slave CPU reset lines, discrete audio triggers, screen flipping, serial EEPROMs and much else. Over 100 drivers and a few bus devices have been updated to use the new implementation, and a great deal of research has gone into documenting the physical location of these devices on actual PCBs in the source. Write handlers have been provided for both orthodox and somewhat less conventional memory mappings.
Incidental to this update, coin counters and/or lockouts have been added to Atari System 1 games, Basketball, Gauntlet, Gyruss, Hana Yayoi, Hole Land, Jr. Pac-Man, Mahjong Sisters, Pooyan, Roc'n Rope, Squash, Thunder Hoop, Time Limit, Time Pilot '84 and many others. This also cleans up coin counter behavior in Sauro and Rally Bike.
(nw) The purpose of committing this change, which has been several months in the making, early in the 0.189GIT cycle will be to allow time for fixing potential regressions; I've fixed a number of drivers that lost sound from this for various reasons (hnayayoi.cpp having missing or garbage ADPCM was particularly painful, since the three games in that driver all work slightly differently), but I can't test all affected drivers exhaustively. @Tafoid, don't bother running automated screen capture comparison tests on this, as many drivers are now expected to have the screen flipped for the first few seconds after reset.
The core changes are:
* Short name, full name and source file are no longer members of device_t, they are part of the device type
* MACHINE_COFIG_START no longer needs a driver class
* MACHINE_CONFIG_DERIVED_CLASS is no longer necessary
* Specify the state class you want in the GAME/COMP/CONS line
* The compiler will work out the base class where the driver init member is declared
* There is one static device type object per driver rather than one per machine configuration
Use DECLARE_DEVICE_TYPE or DECLARE_DEVICE_TYPE_NS to declare device type.
* DECLARE_DEVICE_TYPE forward-declares teh device type and class, and declares extern object finders.
* DECLARE_DEVICE_TYPE_NS is for devices classes in namespaces - it doesn't forward-declare the device type.
Use DEFINE_DEVICE_TYPE or DEFINE_DEVICE_TYPE_NS to define device types.
* These macros declare storage for the static data, and instantiate the device type and device finder templates.
The rest of the changes are mostly just moving stuff out of headers that shouldn't be there, renaming stuff for consistency, and scoping stuff down where appropriate.
Things I've actually messed with substantially:
* More descriptive names for a lot of devices
* Untangled the fantasy sound from the driver state, which necessitates breaking up sound/flip writes
* Changed DECO BSMT2000 ready callback into a device delegate
* Untangled Microprose 3D noise from driver state
* Used object finders for CoCo multipak, KC85 D002, and Irem sound subdevices
* Started to get TI-99 stuff out of the TI-990 directory and arrange bus devices properly
* Started to break out common parts of Samsung ARM SoC devices
* Turned some of FM, SID, SCSP DSP, EPIC12 and Voodoo cores into something resmbling C++
* Tried to make Z180 table allocation/setup a bit safer
* Converted generic keyboard/terminal to not use WRITE8 - space/offset aren't relevant
* Dynamically allocate generic terminal buffer so derived devices (e.g. teleprinter) can specify size
* Imporved encapsulation of Z80DART channels
* Refactored the SPC7110 bit table generator loop to make it more readable
* Added wrappers for SNES PPU operations so members can be made protected
* Factored out some boilerplate for YM chips with PSG
* toaplan2 gfx
* stic/intv resolution
* Video System video
* Out Run/Y-board sprite alignment
* GIC video hookup
* Amstrad CPC ROM box members
* IQ151 ROM cart region
* MSX cart IRQ callback resolution time
* SMS passthrough control devices starting subslots
I've smoke-tested several drivers, but I've probably missed something. Things I've missed will likely blow up spectacularly with failure to bind errors and the like. Let me know if there's more subtle breakage (could have happened in FM or Voodoo).
And can everyone please, please try to keep stuff clean. In particular, please stop polluting the global namespace. Keep things out of headers that don't need to be there, and use things that can be scoped down rather than macros.
It feels like an uphill battle trying to get this stuff under control while more of it's added.

- Separate watchdog implementation from running_machine (once again) and driver_device
- Old-style methods, now hidden behind #ifdefs, will probably be safe to remove soon
nl_convert.c. Targets using netlist must now specify this explicitly
