Peter Seiderer 9b2bbe3422 linux: add fbtft kernel extension
Tested with RaspberryPi B+ and PiTFT Mini Kit - 320x240 2.8" TFT
(see [1] and [2]) and the following target configuration changes:
- cmdline.txt: add 'fbcon=map:10 fbcon=font:VGA8x8'
- add /etc/modules-load.d/fbtft.conf with 'fbtft_device'
- add /etc/modprobe.d/00-fbtft.conf with 'options fbtft_device name=adafruit28 rotate=90 gpios=dc:25'

[2] http://h65951.serverkompetenz.net/PeterSeiderer/upload/PiTFT_2_8_ct/Image9897.jpg

[Thomas:
  - Rename prompt of the Linux extension to "FB TFT drivers"
  - Remove the full name of the kernel config options in the help
    text. Giving their CONFIG_<foo> name is enough.
  - Remove the mention of CONFIG_SPI_BCM2708, since this makes the
    description RaspberryPi specific, while these drivers can work
    with any SPI controller.
  - Refactor the code in linux-ext-fbtft.mk to avoid duplication
    between the < 3.15 and >= 3.15 cases.
  - Make the fbtft package a promptless package, since there is no
    point in selecting only this package, without the kernel
    extension.
  - Change the license to GPLv2, since it's kernel code.]

Optionally, explicitly specify the Adeos patch to use.
Download it at http://download.gna.org/adeos/patches/v2.6/$(ARCH)/
and verify that your kernel version in buildroot matches.

Linux Framebuffer drivers for small TFT LCD display modules,
e.g. Adafruit PiTFT displays for Raspberry Pi.
To enable fbtft, e.g. for Adafruit 2.8 PiTFT, enable the
following kernel configurations:
- CONFIG_SPI
- CONFIG_GPIOLIB
- CONFIG_FB
- CONFIG_FB_TFT
- CONFIG_FB_TFT_ILI9341
