为 cs8900a 建立编译菜单
1. 拷贝到文件
把 cs8900a 的压缩包拷贝到 arm 用户下的 dev_home/localapps/ [arm@localhost localapps]$ tar xzvf cs8900a.tar.gz [arm@localhost localapps]$cd cs8900a
[arm@localhost cs8900a]$cp cs8900a.c $KERNEL/linux2.6.14.1/drivers/net/ [arm@localhost cs8900a]$cp cs8900.h $KERNEL/linux2.6.14.1/drivers/net/
[arm@localhost cs8900a]$vi $KERNEL/linux2.6.14.1/drivers/net/Kconfig
#加入如下内容
config CS8900a
tristate "CS8900a support"
depends on NET_ETHERNET && ARM && ARCH_SMDK2410
help
Support for CS8900A chipset based Ethernet cards. If you have a network (Ether net) card of this type, say Y and read the EthernetHOWTO, available from as well as.
To compile this driver as a module, choose M here and read. The module will be called cs8900.o.
[arm@localhost cs8900a]$vi $KERNEL/linux2.6.14.1/drivers/net/Makefile
#加入如下内容
obj$(CONFIG_CS8900a) += cs8900a.o
修改 S3C2410 相关信息
1. 加入 CS8900A 在内存中的起始位置
[arm@localhost cs8900a]$cp regcs8900.h $KERNEL/linux2.6.14.1/include/asmarm/archs3c2410/ cs8900.h 的内容如下:
#ifndef _INCLUDE_CS8900A_H_
#define _INCLUDE_CS8900A_H_
#include <linux/config.h>
#define pSMDK2410_ETH_IO 0x19000000 /* S3C2410_CS3 0x18000000 */
#define vSMDK2410_ETH_IO 0xE0000000
#define SMDK2410_ETH_IRQ IRQ_EINT9
#endif
2. 加入 cs8900A 的物理地址到虚拟地址的映射
[arm@localhost cs8900a]$vi $KERNEL/linux2.6.14.1/arch/arm/machs3c2410/machsmdk2410.c
/* 加入如下内容 */
static struct map_desc smdk2410_iodesc[] initdata = {
{vSMDK2410_ETH_IO, 0x19000000, SZ_1M, MT_DEVICE} /* Add this line */
};
