3.7 修改UBOOT支持DM9000網卡
3.7.1 搜尋DM9000關鍵字, 發現/driver/net/Makefile中，
如果將dm9000x.c編譯進內核，需要定義 CONFIG_DRIVER_DM9000，因此需修改
smdk2440.h
======================================================
smdk2440.h
/*
* Hardware drivers
*/
#if 0
#define CONFIG_CS8900 /* we have a CS8900 on-board */
#define CONFIG_CS8900_BASE 0x19000300
#define CONFIG_CS8900_BUS16 /* the Linux driver does accesses as shorts */
#else
#define CONFIG_DRIVER_DM9000
#endif
======================================================
3.7.2 重新編譯，發現error如下,
.........
