手把手教你移植linux内核OK6410（三）OK6410--LCD液晶驱动移植：下边来移植一个4.3寸LCD液晶。首先打开我们的板级BSP文件，更改上面的fb部份代码，即液晶配置部份代码[cpp]viewplaincopy1.root@ubuntu:/forlinx/linux-3.3.5/arch/arm/mach-s3c64xx#geditmach-ok6410.c找到staticstructs3c_fb_pd_winok6410_fb_win0这个结构体更改成[cpp]viewplaincopy1.staticstructs3c_fb_pd_winok6410_fb_win0={2./*thisistoensureweusewin0*/3..win_mode={4..left_margin=2,5..right_margin=2,6..upper_margin=2,7..lower_margin=2,8..hsync_len=41,9..vsync_len=10,10..xres=480,11..yres=272,12.},13..max_bpp=32,14..default_bpp=16,15.};不同的液晶对应的配置会不同，具体查看对应液晶的指南。
继续找寻，找到[cpp]viewplaincopy1.staticstructmap_descok6410_iodesc[]={};前面这个结构体是空的linux内核移植教程，我们更改为[cpp]viewplaincopy1.staticstructmap_descok6410_iodesc[]={2.{3..virtual=(unsignedlong)S3C_VA_LCD,4..pfn=__phys_to_pfn(S3C_PA_FB),5..length=SZ_16K,6..type=MT_DEVICE,7.},8.};##################################################################################################将飞凌3.0.1内核（或其它内核）中的drviers/video/下的samsung目录拷贝我们对应的目录中来。更改drviers/video/的Kconfig文件，在文件的最后添加[cpp]viewplaincopy1.source"drivers/video/samsung/Kconfig"更改drviers/video/的Makefie文件,把我们添加进来的文件进行内核编译时同时编译，再最后一行添加：[cpp]viewplaincopy1.obj-$(CONFIG_FB_S3C_EXT)+=samsung/#################################################################################################在arch/arm/plat-samsung/include/plat/map-base.h上面添加[cpp]viewplaincopy1.#defineS3C_VA_LCDS3C_ADDR(0/*LCD*/在include/generated/atuoconfig.h文件最后添加[cpp]viewplaincopy1.#defineCONFIG_FB_S3C_EXT_NUM4在drivers/video/samsung/s3cfb_fimd4x.c文件中的3.0中的对应1438行[cpp]viewplaincopy1.s3c6410_pm_do_save(s3c_lcd_save,ARRAY_SIZE(s3c_lcd_save));更改成[cpp]viewplaincopy1.s3c_pm_do_save(s3c_lcd_save,ARRAY_SIZE(s3c_lcd_save));把1459行，[cpp]viewplaincopy1.s3c6410_pm_do_restore(s3c_lcd_save,ARRAY_SIZE(s3c_lcd_save));更改成[cpp]viewplaincopy1.s3c_pm_do_restore(s3c_lcd_save,ARRAY_SIZE(s3c_lcd_save));保存。
