根据风微柳西的blog文章移植2.6.14的linux内核，编译成功，下载运行的情况如下：
压缩内核zImage下载到0x10000的norflash上。
文件系统romfs.img 下载到0x100000的norflash上。 **************************************

问题： 1，Kernel command line:  没有参数，bootloader的设置参数没有传给它。如果在/arch/arm/kernel/setup.c 里面直接给默认的command line 赋命令，这样系统就跑完bootloader，Linux version 2.6.14-hsc0 这一句开始就不打印了。
2，怎么建立romfs，下载的romfs.img 地址在0x100000，在那个地方告诉uClinux内核的？
3，打印信息没有打印有关内存分区的消息，是不是块会有问题？
