解决方法一
======================================================
Linux 内核启动时出现：bad machine ID，原因大致是u-boot 传递给
内核的machine ID错误，可以手动在内核源代码中添加machine ID.
解决方法：
在u-boot 命令行中输入bdinfo
查看板卡信息，我的输出如下:
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
修改内核的arch/arm/kernel/head.S，直接将s3c2410的参数赋给内核
# 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
解决方法二
======================================================

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