Linux2.6.24.4移植到S3C2410(nano2410)之：CS8900移植

【平台信息】
目标板(Nano2410)------------------------
CPU:    S3C2410X
SDRAM:  HY57V561620(32MB)
FLASH: K9F1208(64MB)
NET:    CS8900

HOST---------------------------------------
Linux Realse Version:     Fecora Cor 8 (FC8)
CrossCompiler:             gcc-4.1.1/glibc-2.3.2


在之前的内核移植基础上，
"
【置顶】Linux2.6.24.4移植到S3C2410(nano2410)之：内核移植篇
"
继续进行CS8900网卡驱动移植。

【移植步骤】
1.       将准备好的cs8900.c, cs8900.h复制到drivers/net/arm文件夹下。（注意，网上大部分cs8900驱动都是针对2.6.14内核的，2.6.24有很大的变动，可以下载本文开头的附件cs8900-linux2.6.24-kevin.tar.bz2。

2.       新建文件smdk2410.h
[kevin@localhost arch-s3c2410]$ pwd
/kevin/linux-2.6.24.4/include/asm-arm/arch-s3c2410
[kevin@localhost arch-s3c2410]$ vim smdk2410.h

添加如下代码：

#define pSMDK2410_ETH_IO        __phys_to_pfn(0x19000000)
#define vSMDK2410_ETH_IO        0xE0000000
#define SMDK2410_EHT_IRQ        IRQ_EINT9
     这些宏在cs8900.c中要用到。

3.    修改mach-smdk2410.c.
[kevin@localhost mach-s3c2410]$ pwd
/kevin/linux-2.6.24.4/arch/arm/mach-s3c2410
      [kevin@localhost mach-s3c2410]$ vim mach-smdk2410.c

include建立的刚才建立的头文件smdk2410.h
#include "asm/arch/smdk2410.h

在map_desc smdk2410_iodesc[]
中添加cs8900的对于的io空间映射

static struct map_desc smdk2410_iodesc[] __initdata = {
  /* nothing here yet */
{ vSMDK2410_ETH_IO , pSMDK2410_ETH_IO, SZ_1M, MT_DEVICE },
};

4.       在/drivers/net/arm/Kconfig中增加menu config中CS8900编译选项
[kevin@localhost arm]$ pwd
/kevin/linux-2.6.24.4/drivers/net/arm
[kevin@localhost arm]$ vim Kconfig

# +kevin 080327
config  ARM_CS8900
        tristate "CS8900 support"
        depends on NET_ETHERNET && ARM && ARCH_SMDK2410
        help
            Support for CS8900A chipset based Ethernet cards. If you have a network (Ethernet) card of this type, say Y and read the Ethernet-HOWTO,available from as well as .To compile this driver as a module, choose M here and read .The module will be called cs8900.o.

这样，在编译配置菜单”Menu config”中的Ethernet网络设备中就可以找到”CS8900 support”的选项了。

5.  在/drivers/net/arm/Makefile中添加

obj-$(CONFIG_ARM_CS8900)        += cs8900.o

6. 执行menu config。 Device drivers->network device support->Ethernet中选择(*)CS8900 support.

7.  编译内核 make zImage


8. 将生成的uImage重新download到开办板SDRAM中再来看看启动信息。
