[0/7] fbdev: Split off code for boot-up logo

Message

Thomas Zimmermann Aug. 29, 2023, 2:15 p.m. UTC

The boot-up logo is a feature of the fbcon console; with only a few
external callers. Move it from the core fbdev code into its own file.

Patches 1 and 2 remove the logo setup from fbdev drivers. The logo
requires a configured output, which is provided by the framebuffer
console. Drivers should not implement their own logo.

Patches 3 to 6 move the code for the boot-up logo into its own file
and add a number of simple cleanups. It's now separate from the core
fbdev code that maintains the display framebuffers.

Patch 7 then removes a number of unecessary include statements from
fbmem.c.
