移植手册中一些数值设置依据

static struct mtd_partition smdk_default_nand_part[] = {
#if defined(CONFIG_EmbedSky_64MB_NAND)
[0] = {
.name = "EmbedSky_Board_uboot",
.offset = 0x00000000,
.size = 0x00040000,
},
[1] = {
.name = "EmbedSky_Board_kernel",
.offset = 0x00200000,
.size = 0x00200000,
},
[2] = {
.name = "EmbedSky_Board_yaffs2",
.offset = 0x00400000,
.size = 0x03BF8000,
}
#elif defined(CONFIG_EmbedSky_128MB_NAND)
[0] = {
.name = "EmbedSky_Board_uboot",
.offset = 0x00000000,
.size = 0x00040000,
},
[1] = {
.name = "EmbedSky_Board_kernel",
.offset = 0x00200000,
.size = 0x00200000,
},
[2] = {
.name = "EmbedSky_Board_yaffs2",
.offset = 0x00400000,
.size = 0x07BA0000,
}
#elif defined(CONFIG_EmbedSky_more_than_256MB_NAND)
[0] = {
.name = "EmbedSky_Board_uboot",
.offset = 0x00000000,
.size = 0x00040000,
},
[1] = {
.name = "EmbedSky_Board_kernel",
.offset = 0x00200000,
.size = 0x00200000,
},
[2] = {
.name = "EmbedSky_Board_yaffs2",
.offset = 0x00400000,
.size = 0x0FB80000,
}
#endif
};
请问offset和size的值是根据什么来设置的。想不明白这些数值是根据什么来定的

这个地方的分区要和uboot的分区相同，这个分区的参数从uboot来的。
