十年磨一劍

點我下載cs8900檔案

[1]把cs8900.c,cs8900.h 拷貝到drivers/net/arm 目錄下
修改cs8900.c中函數int __init cs8900_probe (struct net_device *dev){}
在memset (&priv,0,sizeof (cs8900_t)); 下面新增

__raw_writel(0x2211d110,S3C2410_BWSCON);
__raw_writel(0x1f7c,S3C2410_BANKCON3);

[2]修改drivers/net/arm/Kconfig
$ vi drivers/net/arm/Kconfig

增加以下內容

config ARM_CS8900
tristate "CS8900 support"
depends on NET_ETHERNET && ARM && ARCH_SMDK2410

[3]修改drivers/net/Makefile，增加以下內容︰
$ vi drivers/net/Makefile

obj-$(CONFIG_ARM_CS8900) += cs8900.o

[4]建立smdk2410.h 到include/asm-arm/arch-s3c2410 目錄下
$ vi include/asm-arm/arch-s3c2410/smdk2410.h
smdk2410.h 的內容為 ︰

#ifndef _INCLUDE_SMDK2410_H_
#define _INCLUDE_SMDK2410_H_
#include <linux/config.h>
#define pSMDK2410_ETH_IO 0x19000000
#define vSMDK2410_ETH_IO 0xE0000000
#define SMDK2410_ETH_IRQ IRQ_EINT9
#endif // _INCLUDE_SMDK2410_H_

[5]修改arch/arm/machs-3c2410/mach-smdk2410.c
$ vi arch/arm/mach-s3c2410/mach-smdk2410.c
在static struct map_desc smdk2410_iodesc[] __initdata={}; 內增加以下部分（本來為空）︰
{vSMDK2410_ETH_IO, pSMDK2410_ETH_IO, SZ_1M, MT_DEVICE}

以及增加包含頭檔案
#include <asm/arch/smdk2410.h> //就是建立的那個

[6]在內核配置中選上︰
Device Drivers -->
    Network device support -->
        Ethernet (10 or 100 Mbit)
        〔*〕 CS8900 support.
