这次lcd和触摸屏智能一起移植了，至于原因见详细说明，。主要是一线触摸的原因，它劫持了lcd的背光控制，这个花了我三天时间呀才发现， 友善真是的。
先弄lcd屏吧
vi arch/arm/plat-samsung/include/plat/map-base.h
第39行
增加
#define S3C_VA_LCD S3C_ADDR(0x01100000) /* LCD */
从友善的源码中将arch/arm/mach-s3c64xx/include/mach/regs-lcd.h拷贝过来
从友善的源码中将drivers/video/samsung整个文件夹拷贝过来，是不是有点拿来主义，呵呵
vi drivers/video/Kconfig
第2068行增加
source "drivers/video/samsung/Kconfig"
vi drivers/video/Makefile
120行增加
obj-$(CONFIG_FB_S3C_EXT) += samsung/
vi arch/arm/mach-s3c64xx/mach-mini6410.c
48行增加
#include <linux/delay.h>
136行mini6410_lcd_power_set函数里的内容改成
if (power) {
gpio_direction_output(S3C64XX_GPF(13), 1); //GPF13是USBpower用的，与lcd无关
gpio_direction_output(S3C64XX_GPF(15), 1); //GPF15是是真正的一线控制线连PWM1
/* fire nRESET on power up */
gpio_direction_output(S3C64XX_GPN(5), 0); //GPN5好像与lcd也无关，先copy吧
msleep(10);
gpio_direction_output(S3C64XX_GPN(5), 1);
msleep(1);
} else {
gpio_direction_output(S3C64XX_GPF(15), 0);
gpio_direction_output(S3C64XX_GPF(13), 0);
}
190行
增加
{
/* LCD support */
.virtual = (unsigned long)S3C_VA_LCD,
.pfn = __phys_to_pfn(S3C_PA_FB),
.length = SZ_16K,
.type = MT_DEVICE,
},
437行增加
gpio_request(S3C64XX_GPN(5), "LCD power");
gpio_request(S3C64XX_GPF(13), "LCD power");
去掉gpio_request(S3C64XX_GPE(0), "LCD power");
make menuconfig
Power management options --->
[ ] Power Management support 一定要去掉，不然会有
drivers/video/samsung/s3cfb_fimd4x.c:1440:2: error: implicit declaration of function 's3c6410_pm_do_save'的错误，郁闷了半天
<*> Support for frame buffer devices --->
< > Samsung S3C framebuffer support
<*> S3C Framebuffer Support (eXtended)
Select LCD Type (4.3 inch 480x272 TFT LCD) --->
<*> Advanced options for S3C Framebuffer
Select BPP(Bits Per Pixel) (16 BPP) --->
(4) Number of Framebuffers
[ ] Enable Virtual Screen (NEW)
[*] Enable Double Buffering
[ ] Backlight & LCD device support --->
Console display driver support --->
<*> Framebuffer Console support 这个也一定要选，不然会有
drivers/built-in.o:(.data+0x174): undefined reference to `soft_cursor'的错误，其中解决这些错误花了我不少时间。
[*] Bootup logo --->
[ ] Standard black and white Linux logo
[ ] Standard 16-color Linux logo
[*] Standard 224-color Linux logo
其他的默认就行
这时lcd的驱动其实已经移植好了，引导信息也正常，如
S3C_LCD clock got enabled :: 133.000 Mhz
LCD TYPE :: N43 will be initialized

但lcd屏却没有反应，百思不得其解。后来终于发现了，过程明天在说
先做一线触摸的驱动
拷贝
arch/arm/mach-s3c64xx/dev-ts-mini6410.c
arch/arm/mach-s3c64xx/include/mach/ts.h
arch/arm/plat-samsung/include/plat/regs-adc.h
drivers/input/touchscreen/mini6410_1wire_host.c
drivers/input/touchscreen/mini6410-ts.c
drivers/input/touchscreen/ts-if.c
到相应目录
vi arch/arm/mach-s3c64xx/Makefile
末尾增加
obj-$(CONFIG_TOUCHSCREEN_MINI6410) += dev-ts-mini6410.o
vi drivers/input/touchscreen/Makefile
末尾加入
obj-$(CONFIG_TOUCHSCREEN_MINI6410) += mini6410-ts.o
obj-$(CONFIG_TOUCHSCREEN_1WIRE) += mini6410_1wire_host.o
obj-$(CONFIG_FB_S3C_EXT_TFT800480) += ts-if.o

obj-$(CONFIG_FB_S3C_EXT_X240320) += ts-if.o
vi drivers/input/touchscreen/Kconfig
190行左右加入
config TOUCHSCREEN_MINI6410
tristate "S3C touchscreen driver for Mini6410"

default y
help
Say Y here to enable the driver for the touchscreen on the
FriendlyARM Mini6410 development board.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called mini6410-ts.
config TOUCHSCREEN_1WIRE
tristate "Mini6410 1-Wire host and Touch Screen Driver"
depends on MACH_MINI6410
help
Say Y here to enable the 1-Wire host and Touch Screen driver for
FriendlyARM Mini6410 development board.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called mini6410_1wire_host.
vi arch/arm/mach-s3c64xx/mach-mini6410.c
44行 将#include <plat/ts.h>
改成#include <mach/ts.h>
320行将
static struct s3c2410_ts_mach_info s3c_ts_platform __initdata = {
.delay = 10000,
.presc = 49,
.oversampling_shift = 2,
};
改成
static struct s3c_ts_mach_info s3c_ts_platform __initdata = {
.delay = 0xFFFF,
.presc = 0xFF,
.oversampling_shift = 2,
.resol_bit = 12,
.s3c_adc_con = ADC_TYPE_2,
};
436行将
s3c24xx_ts_set_platdata(&s3c_ts_platform);
改成 s3c_ts_set_platdata(&s3c_ts_platform);
vi arch/arm/plat-samsung/Makefile
60行
注释掉obj-$(CONFIG_SAMSUNG_DEV_TS) += dev-ts.o
不然会有multiple definition of `s3c_device_ts'的错误很奇怪，友善的源码CONFIG_SAMSUNG_DEV_TS=n，而我的源码出来后CONFIG_SAMSUNG_DEV_TS=y，还改不掉。。
vi drivers/input/touchscreen/mini6410-ts.c
增加头文件#include<linux/sched.h> 奇怪的是友善的mini6410-ts.c
里没这个头文件也能找到需要的东西。。。
Input device support --->
[*] Touchscreens --->
<*> S3C touchscreen driver for Mini6410
<*> Mini6410 1-Wire host and Touch Screen Driver
lcd好用了，开机出现了那只小企鹅，挂NFS后触摸屏也能用了。
