解決方法一
======================================================
Linux 內核啟動時出現(xiàn)：bad machine ID,，原因大致是u-boot 傳遞給
內核的machine ID錯誤,，可以手動在內核源代碼中添加machine ID.
解決方法：
在u-boot 命令行中輸入bdinfo
查看板卡信息，我的輸出如下:
FS2410# bdinfo
arch_number = 0x000000C1
env_t = 0x00000000
boot_params = 0x30000100
DRAM bank = 0x00000000
-> start = 0x30000000
-> size = 0x04000000
ethaddr = 08:00:3E:26:0A:5B
ip_addr = 10.1.8.245
baudrate = 115200 bps
修改內核的arch/arm/kernel/head.S,，直接將s3c2410的參數賦給內核
# cd linux-2.6.19
# vi arch/arm/kernel/head.S +72
----------------------------------------------
70 __INIT
71 .type stext, %function
72 ENTRY(stext)

mov r0, #0
mov r1, #0xc1
ldr r2, =0x30000100

73 msr cpsr_c, #PSR_F_BIT | PSR_I_BIT | SVC_MODE @ ensure svc mode

解決方法二
======================================================

修改u-boot,，填寫ID；
# vi common/cmd_boot.c
