-konamim2: Massive update. Most games work, but are still marked non-working due to rare MAME crashes in the PPC DRC. [Phil Bennett, Ryan Holtz]
Used in the high end HP9000/300 machines. Provides a resolution
of 1280x1024 @ 8bpp. It also provides two overlay planes and one
phantom plane. Each plane contains two window movers that are used
for copying characters and tiles on the screen. It also has a RUG
for line/vector drawing. The current state implements everything
that is required to have a working HP Visual user environment in
MAME.
Working:
- window mover
- pixel replacement rules
- window replacement rules
- f0 tripple replacement rule (copy src or keep destination depending on pattern register)
- VRAM bit access mode
- solid line drawing
Not implemented yet:
- drawing circles
- linetype vector/circles
- rectangles
- filling areas
- tripple replacement rules other than f0
-mips3.cpp: Various changes: [Ryan Holtz]

-indigo.cpp: Various changes: [Ryan Holtz]
* Expanded logging.
* Enabled PIT8254 timer. Has the wrong clock value; the correct clock causes a hang.
* Improved RAM layout.
* Added stubs for DSP RAM and Entry-level graphics.
Two sample roms are missing, sad. Volume is not taken into account
yet (because the registers are not yet understood), pan is though.
Don't even think about reverb or effects :-)
Current code plays a scale in a loop. Comment the timer alloc in
machine_reset to kill that.
Demo song (missing lots of sounds, because roms): U then > until demo
then ENTER ENTER.

* [R9751] (Squashed) Early work on SMIOC emulation

Connected SMIOC DMA to 68k
* SMIOC now reading bytes for serial from the 68k memory space successfully.
commit 0f801a05a3fa5b78768a1a2bcb9981466e8f2b0e
Author: Stephen Stair <sgstair@akkit.org>
Date: Tue Mar 27 18:31:32 2018 -0700
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.
commit ca91614fca3f43d87755d0c3439521276d7bfafb
Author: Stephen Stair <sgstair@akkit.org>

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.
* Update address maps to new format.
* SCC2698b: Add tx/rx, baud rate generation
* Emulation improvements for scc2698b device
* MPP output pins emulated
* Improved logging for baud rate changes
* Channel configuration emulated
* Support for TX/RX Enable
* Started integrating new features into SMIOC
* Minor progress on the path to enabling new UART for SMIOC
* 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.
* Disable tracing
* SMIOC: Improving diagnostics and making some progress on the emulation
* Revised tracing in SMIOC and SCC2698B
* Improved tracing approach in r9751
* Minor progress towards working SMIOC emulation.
* [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.
