driver for LCDs based on the Solomon Systech SSD1289 LCD driver. This
of this as a template for an LCD driver that will have to be cusomized
for your particular LCD hardware.
* configs/stm32f4discovery/src/up_extmem.c and up_ssd1289.c: Add support to
STM32F4Discovery for than an external, SSD1289-based LCD.
* configs/stm32f4discovery/nxlines: Add an STM32F4Discovery configuration

=======
I purchased an LCD display on eBay from china. The LCD is 320x240 RGB565 and
is based on an SSD1289 LCD controller and an XPT2046 touch IC. The pin out
from the 2x16 connect on the LCD is labeled as follows:
