MINI2440 configuration specification:

0 - The attached screen is the 3.5" TFT
|
||||
1 - The attached screen is the 7" TFT
|
||||
2 - The VGA Shield is attached (1024x768)
|
||||
Leaving out the screen size parameter will not load
|
||||
the TFT driver, and the framebuffer will be left
|
||||
unconfigured.
|
||||
b - Enable backlight. The TFT backlight pin will be
|
||||
linked to the kernel VESA blanking code and a GPIO
|
||||
LED. This parameter is not necessary when using the
|
||||
VGA shield.
|
||||
c - Enable the s3c camera interface.
|
||||
t - Reserved for enabling touchscreen support. The
|
||||
touchscreen support is not enabled in the mainstream
|

kernel as of 2.6.30, a preliminary port can be found
