The purpose of this patch:
- Adopt the DMA API (jazzsonic, macsonic & core driver).
- Adopt the driver model (macsonic).
This part was cribbed from jazzsonic. As a consequence, macsonic once
again works as a module. Driver model is also used by the DMA calls.
- Support 16 bit cards (macsonic & core driver, also affects jazzsonic)
This code was adapted from the mac68k linux 2.2 kernel, where it has
languished for a long time.
- Support more 32-bit mac cards (macsonic)
Also from mac68k repo.
- Zero-copy buffer handling (core driver)
Provides a nice performance improvement. The new algorithm incidentally
helped to replace the old Jazz DMA code.
The patch was tested on a variety of macs (several 32-bit quadra built-in
NICs, a 16-bit LC PDS NIC and a 16-bit comm-slot NIC), and also on MIPS
Jazz.
