d06d80619e viacuda: Add 1 Sec Timer, fix Get/Set Real Time. 
GET_REAL_TIME was using the wrong offset and wasn't setting out_count.

May need to add time zone offset which could be different between host and guest.
get-time and set-time can be tested in Open Firmware.
SET_REAL_TIME is used by the Date/Time Control Panel when you change the date.
It is unknown what method Mac OS uses to get the time at boot. Mac OS 8.6 does not use GET_REAL_TIME during boot, so the time is left as 12:00 AM Jan 1, 1904.

8a1055ed1b sc53c94: Add DBDMA support. 
- For pdm/amic, real_dma_xfer is called when SCSI_DMA_Ctrl has the run bit set.
- For tnt/grandcentral, dma_wait is called when the DBDMA is started (run bit is set). It will call real_dma_xfer when the phase and sequence are DATA_IN/RCV_DATA or DATA_OUT/SEND_DATA.
- dma_wait and real_dma_xfer uses a one shot timer instead of a loop to continue doing DMA while also giving time to the CPU. This and the above changes handles the case where the DBDMA is started before setting up the transfer phase and sequence.
- dma_stop will stop the one shot timer when the DBDMA channel is stopped.

cf292fafcb control: vram changes. 
Allow VRAM presence only in optional bank.

control: Implement banks.

The BAR is 64MB.
The little-endian/big-endian ranges repeat every 16MB.
An endian range can be addressed in d128 (wide) mode or d64 mode.
In d128 mode, there is a 4MB range followed by an undefined 4MB range. bytes 0..7 belong to the standard bank and bytes 8..15 belong to the optional bank.
In d64 mode:
- 2MB mirror ranges at 0MB and 2MB (both have the same read/write behavor: write to both banks or read from the standard bank.
- 2MB standard bank rage at 4MB.
- 2MB optional bank range at 6MB.

155b8cdad9 atahd: Support inexact CHS. 
The total size needs to have 3 factors cylinders, heads, & sectors. Imagine a disk having a total size with 3 prime factors 3 x 5 x 11. 15 cannot be assigned to heads because that would only leave 11 for sectors and cylinders. Therefore, test all heads and sectors combinations. If the third factor for cylinders is not found, then choose 16 heads, then the minimum number of sectors, and finally the maximum number of cylinders. The loop could be changed to skip values of heads that are not a factor, but it doesn't take any time to try them all.
