Wrong configuration for Portrait orientation

Description

The LCD display is wrong (white screen) if the Portrait mode is selected.

Resolution

In the function BSP_LCD_InitEx (file stm32f469i_discovery_lcd.c), replace the following lines of code:

if(orientation == LCD_ORIENTATION_PORTRAIT)
  {
    VSA  = OTM8009A_480X800_VSYNC;        /* 12 */
    VBP  = OTM8009A_480X800_VBP;          /* 12 */
    VFP  = OTM8009A_480X800_VFP;          /* 12 */
    HSA  = OTM8009A_480X800_HSYNC;        /* 120 */
    HBP  = OTM8009A_480X800_HBP;          /* 120 */
    HFP  = OTM8009A_480X800_HFP;          /* 120 */
    lcd_x_size = OTM8009A_480X800_WIDTH;  /* 480 */
    lcd_y_size = OTM8009A_480X800_HEIGHT; /* 800 */                                
  }
