[PATCH-for-9.1 0/3] ui/display: Introduce API to change console orientation

[Philippe Mathieu-Daudé]

Hi,

The idea behind this series is to reduce the use of the
'graphic_rotate' global. It is only used by the Spitz
machine, so we could convert the '-rotate' argument to
a sugar property on the PXA2XX_LCD_TYPE model, but since
the Spitz machine has been deprecated recently (commit
a2531bb855 "Deprecate various old Arm machine types") it
doesn't seem worthwhile. So just extract the API to change
console orientation.

Regards,

Phil.

I think QemuGraphicConsole is a better place to put the field.
