0b5a798343 atimach64gx: Fix ATI_CRTC_GEN_CNTL.
Add call to crtc_update.
Maybe consider AK and EN bits (placeholder for now).

e3411670cb videoctrl: Add cursor_dirty flag.
If the flag is set when it comes time to draw the cursor again, then call setup_hw_cursor to update the cursor before drawing the cursor.

72b257e5d1 atirage: Improve draw_hw_cursor loops.
- Read 8 bytes at a time instead of just 1.
- Remove multiply operations from loop. We just need increments or additions.
- Change compares with int to compares with zero.

9d0bae2d03 atirage: Add offset to cursor X position.
CUR_HORZ_OFF becomes non-zero when the cursor needs to be drawn to the left of the left edge of the frame buffer.

CUR_VERT_OFF is handled differently. When CUR_VERT_OFF is non-zero, CUR_OFFSET is changed to point to the first line of the cursor that will be drawn, so CUR_VERT_OFF is the number of lines to remove from the total height of the cursor.
Alternatively, we could handle CUR_VERT_OFF the same way as CUR_HORZ_OFF by leaving the cursor height constant, drawing the cursor starting from the CUR_VERT_OFF line, and adjusting cursor Y position by negative CUR_VERT_OFF.

6f231f3367 grandcentral: IOBus changes.
- Add IOBusDevice (nvram_addr_hi_dev) for NVRAM addr hi.
- Add IOBusDevice (nvram_dev) for NVRAM data.
- Make all IOBusDevices use the same code.
- Log error if 4 least significant bits of offset are not zero.
- Correctly byte swap the value before passing it to the IOBusDevice.
- When reading, duplicate the bytes in a word or dword like a real Power Mac does.

7b4d513e22 videoctrl: Add change resolution support.
PDM defaults to 640x480.
If you set --mon_id to MacRGB12in then it would draw 512x384 inside a 640x480 window.
If you set --mon_id to Multiscan20in then it would try to draw 832x624 inside a 640x480 window and crash.
If you set the Monitors control panel to switch multiscan display from 640x480 to 832x624 and  restart then it would crash.
Now it will correctly change the window size every time the mode changes.
