linux-3.4.2移植到FL2440上（二）--修改MTD分区

修改MTD分区：

在/arch/arm/mach-s3c24xx/common-smdk.c

修改：

 1 /* NAND parititon from 2.4.18-swl5 */
 2 
 3 static struct mtd_partition smdk_default_nand_part[] = {
 4     [0] = {
 5         .name    = "Boot Agent",
 6         .size    = SZ_16K,
 7         .offset    = 0,
 8     },
 9     [1] = {
10         .name    = "S3C2410 flash partition 1",
11         .offset = 0,
12         .size    = SZ_2M,
13     },
14     [2] = {
15         .name    = "S3C2410 flash partition 2",
16         .offset = SZ_4M,
17         .size    = SZ_4M,
18     },
19     [3] = {
20         .name    = "S3C2410 flash partition 3",
21         .offset    = SZ_8M,
22         .size    = SZ_2M,
23     },
24     [4] = {
25         .name    = "S3C2410 flash partition 4",
26         .offset = SZ_1M * 10,
27         .size    = SZ_4M,
28     },
29     [5] = {
30         .name    = "S3C2410 flash partition 5",
31         .offset    = SZ_1M * 14,
32         .size    = SZ_1M * 10,
33     },
34     [6] = {
35         .name    = "S3C2410 flash partition 6",
36         .offset    = SZ_1M * 24,
37         .size    = SZ_1M * 24,
38     },
39     [7] = {
40         .name    = "S3C2410 flash partition 7",
41         .offset = SZ_1M * 48,
42         .size    = MTDPART_SIZ_FULL,
43     }
44 };
45 
46 
47 
 1 改为如下：
 2  
 3  /* NAND parititon from 2.4.18-swl5 */
 4  /* by zhutao */
 5  static struct mtd_partition smdk_default_nand_part[] = {
 6      [0] = {
 7         .name    = "U-BOOT",
 8          .size    = SZ_2M,
 9          .offset    = 0,
10      },
11      [1] = {
12          .name    = "KERNEL",
13          .offset = MTDPART_OFS_APPEND,
14          .size    = SZ_4M,
15      },
16      [2] = {
17          .name    = "YAFFS2",
18          .offset = MTDPART_OFS_APPEND,
19          .size    = MTDPART_SIZ_FULL,
20      }
21  };

编译启动内核：

打印信息分区信息：

Creating 3 MTD partitions on "NAND":                                            
0x000000000000-0x000000200000 : "U-BOOT"                                        
0x000000200000-0x000000600000 : "KERNEL"                                        
0x000000600000-0x000010000000 : "YAFFS2"
