tiny6410移植2.6.39内核问题

这两天想学学内核的移植，下了最新版的内核2.6.39.3，先修改了makefile里的ARCH =arm和CROSS_COMPILE =arm-linux-，发现/arch/arm/mach-s3c64xx目录下有mach-mini6410.c文件，里面平台时钟已经是12M了，分区表改成了友善的2.6.38里的，设备表我看它自带的已经很齐全了也没改。然后make menuconfig ,load s3c6400_defconfig，仿照友善的2.6.38内核配置文件config_mini6410_n43改了一通，当然里面有一些选项并不完全一样，但是一样的选项我都配置成相同的了。然后make zimage，下载启动得到以下启动信息，希望各位能指点一下，顺便说一下我用的uboot是MLC NAND Flash的u-boot-2011-06-02。

感觉flash配置不对，初步怀疑是mlc flash的缘故，但要如何修改还望高手指点

还有 Tacls=4, 30ns Twrph0=8 60ns, Twrph1=6 45ns
这个值并不是mach-mini6410.c中配置的值，配置的是
static struct s3c2410_platform_nand mini6410_nand_info = {
    .tacls        = 25,
    .twrph0        = 55,
    .twrph1        = 40,
    .nr_sets    = ARRAY_SIZE(mini6410_nand_sets),
    .sets        = mini6410_nand_sets,
};

难道是说目前2.6.39内核还不支持mlc flash？ nand_isd.c中好像还真是没有大页面的flash,另外在config_mini6410_n43中发现这么一行
CONFIG_INITRAMFS_SOURCE="scripts/FriendlyARM.cpio" 不知道这个脚本干嘛用的

scripts/FriendlyARM.cpio 不是脚本，它可以被解压的，nand flash问题，看到你刚才的回复，相信你已经解决了

恩，nand flash问题已经解决了，已经成功挂载NFS了，只是不知道这个FriendlyARM.cpio 干什么用的

cpio -idmv < FriendlyARM.cpio 一堆乱七八糟的文件夹，我也不知道做什么的

楼主，这问题解决没？kernel BUG at drivers/mtd/nand/nand_base.c:3271! 关键这一句，你把nand_base.c:3271的bug注释掉试下。。

兄弟，，你这个问题是怎么解决的呢？我也正为这个问题郁闷呢，，，可否指点一下，，我QQ994796397，，，，
