93dff23036 Back out the "don't use DMA if SCSI_POLL is set" saftey-net. The 
MI 5380 code did something I didn't really expect, which caused DMA
to disable itself if only DMA was enabled.  *grumble*

edf9d66f32 First-cut support for P4 framebuffers. Currently supports P4 variants 
of bwtwo, cgfour, cgsix, and cgeight.  Includes support for attaching
the overlay plane of the cgfour and cgeight as a bwtwo instance (a'la
SunOS).

P4 register descriptions, cgfour driver, and cgeight driver partially
derived from OpenBSD.

This code may still need polishing.

ef3500b579 Attempt to work around a hardware bug that screws up DMA on the 4/100. 
Apparently, some early 4/100 DMA controllers do illegal memory access on
large ( >= NBPG ) transfers at the end of the transfer.  This appears
as SI_CSR_DMA_BUS_ERR in the csr.  To work around this, we simply
transfer the (up to 3) missing bytes from the bpr.  We were doing this
anyway, so the work-around is to ignore the bus error.

BUT!  I goofed when I implemented the "left-over byte" code for the sw!
It *should* be correct now.  Keep metrics (acceeible via DDB) on the number
of 1, 2, and 3 byte clean-ups, as well as the number of "clean" transfers,
just so we can get a clearer picture.

Thanks to Andrew Gillham <gillham@whirlpool.com> for noticing this!

c86505a6a5 If we get a transfer with the SCSI_POLL flag set, don't use DVMA. We 
only get these during autoconfiguration and during crash dumps.  During
autoconfiguration, the transfers are small enough that DVMA won't be used
anyway.  However, using DVMA during a crash dump can be dangerous,
depending on the nature of the panic, so we avoid it.
