SubjectRe: 2.5.11 framebuffer compilation error
James Simmons writes:

I tried 2.5.12 with this patch on PPC, with most of the mac
framebuffers selected, and got a few errors. Here is a patch that
fixes the compilation errors plus a few other things.

The files affected are:

chipsfb.c )
controlfb.c ) fix compile errors from recent changes
platinumfb.c)
valkyriefb.c)

offb.c fix a problem with colormap corruption on blank
add support for IBM GXT2000P display
fix compile errors from recent changes

aty128.h remove duplicate definition
aty128fb.c add btext_update_display call
add Rage128 Pro TR
eliminate compile warnings
make aty128fb_blank be actually used
add more default resolutions based on
which type of powermac we have

imsttfb.c eliminate compile warning

aty/atyfb_base.c add btext_update_display call

Some of these changes have come from Ben Herrenschmidt.

I have changes to the radeon driver too but I haven't included them in
this patch since I am using version 0.1.4 in my tree at the moment
whereas Linus' tree only has version 0.1.1.

James, it would be good if you could look at this and either apply it,
or let me know if there is anything you don't like so we can discuss
it.

Regards,
Paul.
