#U boot splash code

You’ll notice I started an attempt to generalize my code to support different screen resolutions but got in a time crunch and had to move on. U-Boot will automatically pull in a splash image into its binary it builds. A splash screen is enabled by default, and is shown on the LVDS LCD. There is a frame buffer driver for am335x in the drivers/video directory called am3355x-fb.c. Hopefully you can make some improvements. All the code below is based on Processor Linux SDK 03.02.00.05. To know if your device is supported in U-Boot, check out the respective. I feel like if it is done properly as the U-boot documentation suggests, you might not have this problem. Although the USB drive appears in the boot menu, when clicked the screen goes. With my method, I ended up being able to see garbage in the frame buffer as it gets reset between the bootloader and kernel. However, this isn’t the “right” way as suggested by U-boot with CONFIG_LCD, etc. I just included this driver, and then in the initialization code I called omap3_dss_panel_config(), omap3_fill_framebuffer(), and omap3_dss_enable() and set my GPIOs to turn on the LCD. I modified omap3_dss.c and have a working splash screen in u-boot.
