901e4b0219 Fix IOASIC DMA alignment problems. Buffers not aligned on doubleword (8 
byte) boundaries don't work correctly.  Make use of the SDR0/SDR1 registers
to adjust the buffer alignment when starting the DMA transfer.  Block device
I/O done by the filesystems will usually be aligned correctly, but character
device I/O may not be aligned correctly.  This should fix the problems with
dump(8) failing randomly on DECstations.

a00a9ff012 Convert to use rasops/wsfont, enabling colors. 
For now, only the "putchar" and "copyrows" accelerations are used.

b06e451c53 - No need to include '<machine/autoconf.h>'. 
- Nuke tc_badaddr() check from asc_tc because the existency check is already
  done for real TC devices.
- Nuke tc_badaddr() check from asc_ioasic because it is a builtin device
  found in all of IOASIC DECstations.

392a4acdd7 - Remove temporary hack to recognize PMAGD since SFB+ rendering function 
is found not fully upward compatible to its predecessor.  sfbp.c is now
  under development.

configration of it is compatible enough with PMAGB-BA.

95c618a810 - Fix bogus cursor drawn by sfb_cursor(). From eye-opening input from R.C. 
Dowdeswell.

  enough from src. for copying rows.

fd3561cc02 Preliminary import of 'SFB enhanced' text renderer with many caveats 
to be corrected.  Text drawing is now improved significantly, but;
cursor is drawn incorrectly, copycols() trashes a screen, 'standout
(\033[7m)' results in lines reversed entirely until '\033[0m', and
possibly more issues.  Not multi-colour, 8bpp only this moment.  Costly
write memory barrier instrunctions should be eliminated using framebuffer
address aliasing technique for NetBSD/alpha.

8dd0e06ba1 - Hide memory mapped VDAC hardware register layouts using the array 
element access instead of C bitfield (hello, BCPL).
- XXX Some TURBOchannel framebuffers might need shutdownhooks().  It
seems not necessarily hardware sprite cursor images are re-initialized
by DECstation PROMs upon exits from kernel.
- XXX It'd be an arguable point to allow user programs to change the
shade of gray freely for pixel value 0 and 1.

manipulation.

3adf25374a The extraneous interrupt that seems to occur after a reconnect and a DMA transfer 
starts running can occur on both DMA in and DMA out.  I missed the little comment
in the Mach driver for the DMA out case.  Also, only ignore the interrupt if the
TC is non-zero (to match the Mach driver).

cff0f6b1e4 Don't pre-load the identify message into the fifo just just before the command register 
is written.  This significantly reduces, if not eliminates, the problem reported in
PR#5510.  It stops the problem on my 5000/200, and two other people have verified that
it fixes the problem on their 5000/200s.  I'm waiting for confirmation from the PR
originator before closing the PR.
