[Qemu-devel] [PATCH 0/2] sun4m: Implement Sun CG3 framebuffer for QEMU

[Mark Cave-Ayland]

This patchset follows on from the previous "Add FCode ROM for TCX framebuffer"
patch and provides QEMU with an implementation of the Sun CG3 8-bit
framebuffer. It is based upon Bob Breuer's original work which has been
rebased onto git master, and is now capable of running with an OpenBIOS CG3 
FCode ROM instead of requiring copies of proprietary Sun ROMs.

Note this patch has been around for a month or so but has been waiting for the 
updated OpenBIOS images to be included in QEMU. Therefore while it has not yet 
been reviewed, it is a reasonably simple and self-contained patchset
and has been updated to reflect the comments received from the associated
"Add FCode ROM for TCX framebuffer" patch. For this reason, I feel that both
these patches are a candidate for 1.7.

The motivation behind this patch is that older operating systems such as
Debian Woody and Solaris (running OpenWindows) do not contain drivers for the
TCX framebuffer and as a result currently cannot run in graphical mode. The
screenshots linked below show qemu-system-sparc successfully running both 
Debian Woody and the Solaris 8 installer in graphical mode during testing:

The CG3 framebuffer is selected by passing -vga cg3 on the command line to
qemu-system-sparc. If either -vga tcx is specified (or the -vga argument is
omitted) then qemu-system-sparc defaults to using the existing TCX
framebuffer to maintain compatibility.
