Uboot跟kernel对于Nandflash分区

Uboot和kernel对于Nandflash分区
1. Uboot没有对Nandflash进行分区，通过bootargs参数将file system信息传递给kernel

2. 在kernel中对Nandflash分区信息：
arch/arm/mach-s3c6410/mach-smdk6410.c中

struct mtd_partition s3c_partition_info[] = {
        {
                .name           = "Bootloader",
                .offset         = 0,
                .size           = (512*SZ_1K),
                /* .mask_flags  = MTD_CAP_NANDFLASH, */
        },
        {
                .name           = "Kernel",
                .offset         = (512*SZ_1K),
                .size           = (8*SZ_1M),
                /* .mask_flags  = MTD_CAP_NANDFLASH, */
        },
        {
                .name           = "File System",
                .offset         = (8*SZ_1M + 512*SZ_1K),
                .size           = (128*SZ_1M),
        },
        {
                .name           = "User",
                .offset         = MTDPART_OFS_APPEND,
                .size           = MTDPART_SIZ_FULL,
        }
};

struct s3c_nand_mtd_info s3c_nand_mtd_part_info = {
        .chip_nr = 1,
        .mtd_part_nr = ARRAY_SIZE(s3c_partition_info),
        .partition = s3c_partition_info,
};
3. 分区信息存放在Nandflash的最后一块
