nand.h文件里有8bit ECC的相关定义，不要高兴的太早，这里面是有错滴，不知道是不是飞凌那边故意搞错的，还是本来就不是6410的。
且看定义：
#define NF_ECC_8BIT_STOP() {g_pNFConReg->NFCONT |= (1<<12);} //stop the last encode or decode of 8bit mode.
对比文档看一下这个NFCONT[12]是干什么的
NFCONT[11]这个才是8bitStop，但为什么源码中要定义NFCONT[12]为NF_ECC_8BIT_STOP，这个容易让人产生误解。咱还是改一下吧！
#define NF_ECC_8BIT_STOP() {g_pNFConReg->NFCONT |= (1<<11);}
