[PULL 21/49] ati-vga: Implement foreground and background color register writes

Posted by Philippe Mathieu-Daudé 1 month ago

From: Chad Jablonski <chad@jablonski.xyz>

These are straightforward 32-bit register write handlers. They're
necessary for a future patch which will use them for color expansion
from monochrome host data transfers.
