skyeye 实现了u-boot的nand命令，但是不能找到nand device。。。
启动信息是：**************************** WARNING **********************************
If you want to run ELF image, you should use -e option to indicate
your elf-format image filename. Or you only want to run binary image,
you need to set the filename of the image and its entry in skyeye.conf.
***********************************************************************
Non-option argument skyeye.conf
Your elf file is little endian.

SMDK2410 # nand
Usage:
nand - NAND sub-system 另外我用了mknandflashdump 把u-boot映像到了nand.dump中。（未映像时调用 skyeye -c skyeye.conf 也会生成个nand.dump文件，这是为什么呢？） 呼。。。问题解决了。。。是u-boot编写nand_flash.c时的问题。。。重写board_nand_init后解决。。:-D
