Add AVR32 LCD support
This patch adds support for the AVR32 LCD controller. This patch is
based off the latest u-boot-video.
A quick summary of what's going on:-
Enable LCDC pixel clock
Enable LCDC port pins
Add framebuffer pointer to global_data struct
Allocate framebuffer
To use the new code, update your board config to include something like
this:-
#define CONFIG_LCD 1
#if defined(CONFIG_LCD)
#define CONFIG_CMD_BMP
#define CONFIG_ATMEL_LCD 1
#define LCD_BPP LCD_COLOR16
#define CONFIG_BMP_16BPP 1
#define CONFIG_FB_ADDR 0x10600000
#define CONFIG_WHITE_ON_BLACK 1
#define CONFIG_VIDEO_BMP_GZIP 1
#define CONFIG_SYS_VIDEO_LOGO_MAX_SIZE 262144
#define CONFIG_ATMEL_LCD_BGR555 1
#define CONFIG_SYS_CONSOLE_IS_IN_ENV 1
#define CONFIG_SPLASH_SCREEN 1
#endif
The standard U-Boot BMP and Splash-screen features should just work.
