The frame buffer device uses the following fields:

- pixclock: pixel clock in ps (pico seconds)

- left_margin: time from sync to picture

- right_margin: time from picture to sync

- upper_margin: time from sync to picture

- lower_margin: time from picture to sync

- hsync_len: length of horizontal sync

- vsync_len: length of vertical sync

在内核编译配置选项中选择：

Device Drivers ---> Graphics support --->

<*> Support for frame buffer devices --->

<*> S3C2410 LCD framebuffer Support

[*] S3C2410 lcd debug messages

[*] Backlight & LCD device support --->

<*> Samsung LTV350QV LCD Panel

[*] Bootup logo --->

[*] Standard 224-color Linux logo (NEW)

make uImage -j4

启动内核，LCD既可以显示linux kernel 小企鹅了。
