.partitions = eilian240_nand_part,
.flash_bbt = 1, /* we use u-boot to create a BBT */
},
};
static struct s3c2410_platform_nand eilian240_nand_info __initdata = {
.tacls = 20,
.twrph0 = 60,
.twrph1 = 20,
.nr_sets = ARRAY_SIZE(eilian240_nand_sets),
.sets = eilian240_nand_sets,
.ignore_unset_ecc = 1,
};
将nand flash 设备注册到系统中
static struct platform_device *eilian240_devices[] __initdata = {
&s3c_device_ohci,
&s3c_device_lcd,
&s3c_device_wdt,
&s3c_device_i2c0,
&s3c_device_iis,
&s3c_device_nand,
};
传入eilian240_nand_info结构体初始化参数到内核中去
static void __init eilian240_machine_init(void)
{
s3c24xx_fb_set_platdata(&eilian240_fb_info);
s3c_i2c0_set_platdata(NULL);
s3c_nand_set_platdata(&eilian240_nand_info);
platform_add_devices(eilian240_devices, ARRAY_SIZE(eilian240_devices));
// smdk_machine_init();
}
加入必要的头文件
