For now, it just contains the hack for cirrusfb on Amiga, which is moved out of <video/vga.h> with some slight modifications (use raw_*() instead of z_*(), which are defined on all m68k platforms). This makes it safe to include <video/vga.h> in all contexts. Before it could fail to compile with include/video/vga.h: In function ‘vga_mm_r’: include/video/vga.h:242: error: implicit declaration of function ‘z_readb’ include/video/vga.h: In function ‘vga_mm_w’: include/video/vga.h:247: error: implicit declaration of function ‘z_writeb’ include/video/vga.h: In function ‘vga_mm_w_fast’: include/video/vga.h:253: error: implicit declaration of function ‘z_writew’ or include/video/vga.h:23:21: error: asm/vga.h: No such file or directory depending on the value of CONFIG_AMIGA.
