Initial implementation of ATA device drivers
...
ATA device drivers act as virtual devices attached to ATA channels. They typically interact with real hardware by accessing a hard drive image, an XISO, a host DVD drive or similar methods.
Implemented two ATA device drivers:
- Null: absence of a device (cable disconnected)
- Dummy: a fake, empty hard drive (still incomplete; mostly to aid development)
Added ATA device drivers to the Xbox class. They need to be made configurable later.
Implemented the command processing part of the Identify Device command. Still need to implement the data buffer and reading from the buffer.
Allow 8-bit and 32-bit reads from and writes to the Data register
Reads from various command registers will now return 0 if there is no device attached to the selected port. Only the Status register is valid in this case. Writes go through but are largely ignored.
