4、修改driver/video/videomodes.c，添加相应分辨率

const struct ctfb_vesa_modes vesa_modes[VESA_MODES_COUNT]添加如下成员

{0x31B, RES_MODE_1280x1024, 24},

{0x211, RES_MODE_240x320, 16},

{0x212, RES_MODE_480x272, 16},

{0x213, RES_MODE_800x480, 16},

const struct ctfb_res_modes res_mode_init[RES_MODES_COUNT]添加成员函数

{240, 320, 90000, 1, 4, 1, 1, 30, 4, 0, FB_VMODE_NONINTERLACED},

{480, 272, 75000, 2, 3, 1, 1, 40, 1, 0, FB_VMODE_NONINTERLACED},

{800, 480, 50000, 2, 2, 2, 2, 41, 4, 0, FB_VMODE_NONINTERLACED},

5、修改driver/video/videomodes.h

修改#define CONFIG_SYS_DEFAULT_VIDEO_MODE 0x212//0x301

添加：

#define RES_MODE_240x320 6

#define RES_MODE_480x272 7

#define RES_MODE_800x480 8

#define RES_MODES_COUNT 9

修改：#define VESA_MODES_COUNT 22//19

6、include/asm-arm/s3c6400.h

添加

#define ELFIN_FB_BASE 0x77100000

#define LCD_SEL 0

#define LCD_SEL_MASK 0x03

static inline s3c64xx_fb *s3c64xx_get_base_fb(void)

{

return (s3c64xx_fb *)(ELFIN_FB_BASE);

}

7、include/asm-arm/s3c64x0.h

添加：

typedef struct {

volatile u32 VIDCON0;

volatile u32 VIDCON1;

volatile u32 VIDCON2;

volatile u8 res1[4];

volatile u32 VIDTCON0;
