[PATCH v6 0/8] ati-vga fixes

[BALATON Zoltan <balaton@eik.bme.hu>]

OK I think these are all the fixes I'd like to add for 11.0 unless
some more bugs are found. Could you please check and merge?

v6:
- revert part of mouse pointer fix patch from v5 as it broke MacOS;
since I'm not sure the Linux image has no issues on real machine I'm
not trying to fix that now

v5:
- fix typo on Patch 6
- add more patches to fix mouse pointer with big endian frame buffer

v4:
- compile fix in patch 5
- new patch 6 to work around fuloong2e issue:
https://lists.nongnu.org/archive/html/qemu-devel/2026-01/msg06308.html
v3:
- fix patch 1 to work with 8 and 16 bit modes too
- new patch 5 to fix display updates with 8 and 16 bit modes
v2:
- fix patch 4 to really avoid warnings

These are some fixes to ati-vga for 11.0.

Patch 1 fixes problem reported in
https://lists.nongnu.org/archive/html/qemu-ppc/2026-01/msg00105.html

Patch 2 fixes output from Solaris install iso
Rendering still not always correct as it uses some unimplemented
features but it's now readable. I did not test full install though.

Patch 3 fixes vram overrun errors seen with Solaris and MorphOS when
crtc offset is non-zero (this happens on MorphOS when additional
screen is opened)

Patch 4 tries to avoid Coverity warning matching what other places
already do

Patch 5 fixes dirty region tracking when guest display depth is not
the same as the host's

Patch 6 adds work around for fuloong2e to keep working with partial
machine model
