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.
