bf03576620 Remove driver as unused.

0ee4b22d75 Port over mmap routine from syscons. This lets X11 work on PowerPC with vt. 
The last obstacle to switching PowerPC entirely to vt is that the Playstation 3
framebuffer driver needs to be ported over. This only applies for powerpc64,
however.

015ac42e4b Make ofwfb not be painfully slow. This reduces the time for a verbose boot 
on my G4 iBook by more than half. Still 10% slower than syscons, but that's
much better than a factor of 2.

The slowness had to do with pathological write performance on 8-bit
framebuffers, which are almost universally used on Open Firmware systems.
Writing 1 byte at a time, potentially nonconsecutively, resulted in many
extra PCI write cycles. This patch, in the common case where it's writing
one or several characters in an 8x8 font, gangs the writes together into
a set of 32-bit writes. This is a port of r143830 to vt(4).

The EFI framebuffer is also extremely slow, probably for the same reason,
and the same patch will likely help there.

bdf49e3953 Make ofwfb actually work again. Apparently the API it was written against 
still exists but is now silently ignored by the VT core. At least xboxfb
needs similar changes.

43336b6385 No EFI on i386. This unbreaks the i386 VT kernel build. 2014-04-27 20:36:19 +00:00

7ff9cf1d06 Disable vga if EFI framebuffer present. vt(9) should handle this internally 
based on efifb's higher priority, but it doesn't, and this at least lets
us build a kernel that boots on both BIOS and EFI systems for now.

1da9f0d73a o Add new vd_driver method to do bitblt with mask, named vd_maskbitbltchr. 
o Move vd_bitbltchr vga's driver method to vd_maskbitbltchr.
o Implement new vd_bitbltchr method for vga driver. (It do single write for 8
	pixels, have to be a bit faster).
