Unable to handle kernel NULL pointer dereference at virtual address 00000018
pgd = c0004000
[00000018] *pgd=00000000
Internal error: Oops: 5 [#1]

参考drivers/mtd/nand/s3c2410.c
Flash参数似乎没有传过去，手动添加传值：
mach_mini2440.c
static void __init mini2440_machine_init(void)
{
        s3c_device_nand.dev.platform_data = &mini2440_nand_info;
