If I want to transfer data in frame buffer to LCD GRAM, where should I add this function to?

fb_write() is called by the virtual filesystem itself. You do not call
this directly.

To transfer contents to/from framebuffer, you might need to make code
that will periodically do a memcopy (or similar) that is triggered
perhaps by a timer or during vsync/vblank.
