1   在arch/arm/mach-s3c2410/mach-smdk2410.c中添加
//lcd
#include <asm/arch/regs-lcd.h>
#include <asm/arch-s3c2410/fb.h>
//lcd
static struct s3c2410fb_mach_info s3c2410_lcd_info __initdata ={
  .fixed_syncs = 0,
  .regs = {
   .lcdcon1 = S3C2410_LCDCON1_TFT16BPP |
     S3C2410_LCDCON1_TFT |S3C2410_LCDCON1_CLKVAL(3),
   .lcdcon2 = S3C2410_LCDCON2_VBPD(2) |
     S3C2410_LCDCON2_VFPD(70)|S3C2410_LCDCON2_VSPW(2) ,   
   .lcdcon3 = S3C2410_LCDCON3_HBPD(30) | S3C2410_LCDCON3_HFPD(15) ,
   .lcdcon4 = S3C2410_LCDCON4_MVAL(13) | S3C2410_LCDCON4_HSPW(8),
   .lcdcon5 = S3C2410_LCDCON5_FRM565 | S3C2410_LCDCON5_INVVLINE
     | S3C2410_LCDCON5_HWSWP | S3C2410_LCDCON5_PWREN
     |S3C2410_LCDCON5_INVVFRAME,
  },
  .lpcsel = 0x0,
  .gpccon = 0xaaaaaaaa,
  .gpccon_mask = 0xffffffff,
  .gpcup = 0x0,
  .gpcup_mask = 0xffffffff,
  .gpdcon = 0xaaaaaaaa,
  .gpdcon_mask = 0x0,
  .gpdup = 0x0,
  .gpdup_mask = 0xffffffff,
  .width = 320,
  .height = 240,
  .xres = {320,320,320},
  .yres = {240,240,240},
  .bpp = {16,16,16},
};
//lcd init
static void __init smdk2410_lcd_init(void)
{
 set_s3c2410fb_info(&s3c2410_lcd_info);
}
2   在文件最后MACHINE_END之前添加
.init_machine = smdk2410_lcd_init，
3   编译内核，选中所装驱动
#make menuconfig
Device Drivers >
       Graphics support  ---> 
            <*> support for frame buffer devices
            <*> S3C2410 LCD framebuffer support
                Logo configuration  --->  //开机画面的选择，可据个人需要更改
                    [*]Bootup logo
                    [*]Standard 224-color linux logo
4   开机画面的选择
首先把要开机Logo图片(png格式)放在linux2.6.14文件中的 drivers/video/logo中，终端选择进入drivers/video/logo目录，进行以下操作：
(假设开机图片名为linux.png)
# pngtopnm  linux.png  >  linuxlogo.pnm
# pnmquant 224 linuxlogo.pnm  >  linuxlogo224.pnm
# pnmtoplainpnm  linuxlogo224.pnm  >  linuxlogo224.ppm
# mv  linuxlogo224.ppm  logo_linux_clut224.ppm  //替换原来的启动文件

去掉10 分钟关闭LCD 的方法：
注释掉drivers\char\vt.c 的blank_screen_t(unsigned long dummy)的函数内容,否则,lcd 会在10 分钟左右关掉显示
