bfeeffbb4f cfag12864bfb: Use sys_ instead of cfb_ framebuffer accessors
Because the framebuffer memory is allocated system RAM, use the sys_ drawing
libraries. It also fixes the following compile error:

  LD      .tmp_vmlinux1
drivers/built-in.o:(.data+0x8b48): undefined reference to `cfb_fillrect'
drivers/built-in.o:(.data+0x8b50): undefined reference to `cfb_copyarea'
drivers/built-in.o:(.data+0x8b58): undefined reference to `cfb_imageblit'

[adaplas]
Use fb_sys_read/write for the same reasons as above.

34173a4aad [PATCH] cfag12864b: fix crash when built-in and no parport present
The problem comes when ks0108/cfag12864b are built-in and no parallel port is
present.  ks0108_init() is called first, as it should be, but fails to load
(as there is no parallel port to use).

After that, cfag12864b_init() gets called, without knowing anything about
ks0108 failed, and calls ks0108_writecontrol(), which dereferences an
uninitialized pointer.

Init order is OK, I think.  The problem is how to stop cfag12864b_init() being
called if ks0108 failed to load.  modprobe does it for us, but, how when
built-in?

70e840499a [PATCH] drivers: add LCD support
Add support for auxiliary displays, the ks0108 LCD controller, the
cfag12864b LCD and adds a framebuffer device: cfag12864bfb.

- Add a "auxdisplay/" folder in "drivers/" for auxiliary display
  drivers.

- Add support for the ks0108 LCD Controller as a device driver.  (uses
  parport interface)

- Add support for the cfag12864b LCD as a device driver.  (uses ks0108
  LCD Controller driver)

- Add a framebuffer device called cfag12864bfb.  (uses cfag12864b LCD
  driver)

- Add the usual Documentation, includes, Makefiles, Kconfigs,
  MAINTAINERS, CREDITS...

- Miguel Ojeda will maintain all the stuff above.
