abe0c14301 scsibus: push_data of zero bytes is ok. 
It just means the data hasn't been put on the fifo yet.

782a8d2c3c sc53c94: CMD_COMPLETE_STEPS includes INTSTAT_SO. 
Last step of CMD_COMPLETE_STEPS includes INTSTAT_SO to indicate to CurioSCSIController::fsmCompleting that it returned both a status byte and a message byte in the FIFO.

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.
