leo 7f0e5ecf77 - Fixup the ipending function for the Falcon. This seemed to be the source 
of a lot of instability problems on the Falcon. I also enabled DMA on
  interrupt basis for the Falcon.
- Try to handle targets that request too much data more sanely.
- Some fixups for strict prototypes + -Wall

Thanks to Markus Kilbinger for providing the debugging support.

thorpej 09407a4201 Document the VM86 option by adding it to the GENERIC* kernel config 
files.  Note, the option is disabled by default (comment out).  This
is meant as an example for others.

is 07beed1117 Fix an obvious typo (wrong sign of test). At the same time, make the early 
probe printf prefix unambiguous.

scottr 18fd76201e We don't need to enforce the MAX_DMA_SIZE limit in dma_alloc(); 
this is handled properly by sbc_drq_intr() already.

scottr 2e936aa8ff - Remove several hacks that didn't do much but waste cycles. 
- Disable interrupt-driven PDMA when writing (use polled PDMA instead).
- Be more careful about when to flag a transfer as completed.

The result of these changes is that interrupt-driven PDMA works well
enough to bring the system up.

thorpej aff40e2a72 Break up the ep driver into isa, eisa, and pci front-ends and a 
bus-independent core driver.  Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>

christos 0ca6a87952 Remove memset.c; it is not currently used, and .c files should belong in 
the MI portion of libkern. When/if we move to use mem* routines in the kernel
we can add it to the MI portion/write a memset.s.

veego 112379ef29 Added some ifdef's for RETINA_SPEED_HACK 
Argh, why is a fuction from the RetinaZ2 console driver in the console
driver for the RetinaZ3 ? Fixed.
Fixed some warnings from -Wall if you don't use -DDEBUG

pk ee8f3dc1b8 Turn delay() into a calibrated loop. It's more accurate and compiles into 
a `leaf' routine, avoiding unexpected large delays by overflowing the

race condition exists which makes the internal serial drop incoming
characters under heavy load.

is 5b809af42a Changed the speed calculations of the Amiga-builtin-serial driver to 
allow any baudrate the hardware allows, and to forbid two baudrates
(50 and 75) which the hardware does NOT support but which the old
speed conversion table pretended to support.

chuck edda199ab0 patch from: Steve Woodford <steve@mctavish.demon.co.uk> 
fixes the following problems:
   - Timeout on START/STOP unit command (ie. when spinning up the drive)
     Side effect of this fix is to reduce the busy-wait time in CMD phase.

   - Occasionally, the driver would lose an SBIC interrupt, especially when
     a tape drive was re-selecting on a busy SCSI bus.

scottr 509ace1016 Handle internal video interrupts on RBV-based machines differently so 
that Ethernet cards have a chance to work.  In particular, this change
has been tested on the IIci, IIsi, and LCIII.  The crucial info behind
this code was the result of a lot of work by Julian Bean.

abrown 6b768c677a Now that we have lehwinit() for the Sun4m, make sure that we wait 20ms 
after changing the cable type, as specified in the chip documentation.
Also, sanity-check that sc_dma is valid in case a Sun4m ever exists without
a ledma.
