Hi!
You would place it in drivers/video. If you look at the Config.in file in the linux/drivers/video directory you will see
if [ "$CONFIG_PPC" = "y" ]; then bool ' Open Firmware frame buffer device support' CONFIG_FB_OF ... fi
Just add you driver in that section. Also you have to alter fbmem.c. You need to add something like
extern int xxxmydriverfb_init(void); extern int xxxmydriverfb_setup(char*);
and further down in the file.
#ifdef CONFIG_FB_MYDRIVER { "myfbdriver", xxxmydriverfb_init, xxxmydriverfb_setup }, #endif
When you look at this file you will see what I mean. If you have any further questions just go to http://www.linux-fbdev.org. In this email you will see the address for our mailing list. On our web site it gives you info about joining the mailing list.
