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.

This patch makes tms380tr use the new DMA API. Now that on Alpha, this API
also supports bus master DMA for ISA (platform) devices, i changed the
driver to use this new API.
This also works around a bug in the firmware loader: The example provided
in Documentation/firmware_class no longer works, as the firmware loader now
calls get_kobj_path_length() and the kernel promptly oopses, as the
home-grown device doesn't have a parent. Of course, this doesn't happen
with a "real" device which has its bus (or pseudo bus in the case of
platform) as parent.
Converted tms380tr to use new DMA API:
- proteon.c, skisa.c: use platform pseudo bus to create a struct device
- Space.c: delete init hooks
- abyss.c, tmspci.c: pass struct device to tms380tr.c
- tms380tr.c, tms380tr.h: new DMA API, use real device fo firmware loader

The options FMV18X and SK_G16 do depend on the non-available
CONFIG_OBSOLETE even in kernel 2.4 - IOW, the last time it was able to
select them was in kernel 2.2 (or even before).
Since it seems noone misses these drivers, this patch removes them.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
