linux2.6.22支持网络

1： 内核支持ramdisk：
其中主要修改3项，如下：
①、修改Bootoptions
 Default kernel command string  这一项我设为空，让bootloader(u-boot,vivi)传入。
 
②、选上 Float point emulation ->
[ * ] NWFE math emnulaiton
 
③、修改Driver device  ->
   Block device ->
(4096)Default RAM disk size (kbytes)
改4096为8192

2:net
拷贝cs8900.c .h 到/driver/net
更改make file　添加obj-$(CONFIG_CS8900) += cs8900.o
kconfig文件
config CS8900
    tristate "CS8900 support"
    depends on NET_PCI && (ISA || MACH_IXDP2351 || ARCH_IXDP2X01 || ARCH_PNX010X||MACH_F2410)
    ---help---
      Support for CS8900 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.

config NET_PCI
depends on NET_ETHERNET && (ISA || EISA || PCI||MACH_F2410)

新增文件asm-arm/arch-s3c2410/mach-f2410.h
  /* CS8900 */
 #define S3C24XX_VA_CS8900   0xE0000000
 #define S3C2410_PA_CS8900     __phys_to_pfn(0x19000000)
 #define S3C24XX_SZ_CS8900    SZ_1M
 #define S3C24XX_PA_CS8900    S3C2410_PA_CS8900

#define SMDK2410_ETH_IRQ         IRQ_EINT9


添加arch/arm/mach-s3c2410/mach-f2410.c（拷贝一份mach-smdk.c文件）

添加#include "arch/arm/mach-f2410.h"
static struct map_desc f2410_iodesc[] __initdata = {
       /* nothing here yet */
        /* Map the ethernet controller CS8900A */      
        {S3C24XX_VA_CS8900, S3C2410_PA_CS8900 ,S3C24XX_SZ_CS8900, MT_DEVICE}
};
并修改分区和ｖｉｖｉ对应相等的分区信息
编辑 arch/arm/tools/mach-types增加板子 类型
 修改arch/arm/mach-s3c2410/kconfig 和Makefile文件，添加对f2410的支持
