移植開發實戰指南...有點問題

我依照此文件修改所取得的kernel ,
修改到 mach-mini2440.c這個文件,
說要加入nand 分區的訊息,
我也依照說明加入.
但是compiler 的時候就會出現很多錯誤
arch/arm/mach-s3c2440/mach-mini2440.c:50: error: array type has incomplete element type
arch/arm/mach-s3c2440/mach-mini2440.c:51: error: array index in non-array initializer

以下略...

請問這哪裡出了問題呢?

找到問題了,把頭文件加了就可以過..
但是運行的時候並沒有文件上的訊息,
而是如下訊息:
S3C24XX NAND Driver, (c) 2004 Simtec Electronics
s3c24xx-nand s3c2440-nand: Tacls=4, 39ns Twrph0=8 79ns, Twrph1=8 79ns

pgd = c0004000
[00000004] *pgd=00000000
Internal error: Oops: 5 [#1]

有人知道怎麼回事嗎??
