arm－linux的镜像编译问题

以下是源码，镜像是生成了，但下载到nand里面，一开机就停留在logo了，那些warning是什么意思呢？
root@ubuntu:/opt/EmbedSky/linux-2.6.30.4# make zImage
CHK include/linux/version.h
make[1]: “include/asm-arm/mach-types.h”是最新的。
CHK include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-arm
CALL scripts/checksyscalls.sh
<stdin>:1097:2: warning: #warning syscall fadvise64 not implemented
<stdin>:1265:2: warning: #warning syscall migrate_pages not implemented
<stdin>:1321:2: warning: #warning syscall pselect6 not implemented
<stdin>:1325:2: warning: #warning syscall ppoll not implemented
<stdin>:1365:2: warning: #warning syscall epoll_pwait not implemented
CHK include/linux/compile.h
Kernel: arch/arm/boot/Image is ready
Kernel: arch/arm/boot/zImage is ready

这些Warning可以忽略，内核无法启动的例子论坛上有很多，先搜索一下论坛吧

谢谢！！

这是提示信息，论坛上的帖子基本上都看了，那些设置我这上面貌似没有，很多也看不怎么懂，麻烦版主帮我分析一下
