(Mango64 & kernel) 이더넷 디바이스 드라이버 살리기

망고64는 이더넷이 BANK4에 연결이 되어 있습니다. 따라서,

타이밍을 조절하는 코드를 수정해야 합니다.

\arch\arm\plat-s3c\include\plat\map-base.h에 추가

#define S3C_VA_SMSC9220 S3C_ADDR(0x03b00000) /* SMSC911X */

drivers\net\smsc911x.c에 추가

static int __devinit smsc911x_drv_probe(struct platform_device *pdev) { struct net_device *dev; struct smsc911x_data *pdata; struct smsc911x_platform_config *config = pdev->dev.platform_data; struct resource *res; unsigned int intcfg = 0; int res_size; int retval; DECLARE_MAC_BUF(mac); pr_info("%s: Driver version %s.\n", SMSC_CHIPNAME, SMSC_DRV_VERSION); #if defined(CONFIG_MACH_SMDK6410) || defined(CONFIG_MACH_MANGO6410) // Mango64 set_irq_type(IRQ_EINT(11), IRQ_TYPE_LEVEL_LOW); #endif

arch\arm\plat-s3c64xx\devs.c 의 .name과

#define SMSC_CHIPNAME "smsc911x"(drivers\net\smsc911x.c)

이름이 동일해야 합니다.

struct platform_device s3c_device_smc911x = { .name = "smsc911x", .id = -1, .num_resources = ARRAY_SIZE(s3c_smc911x_resources), .resource = s3c_smc911x_resources, .dev = { .platform_data = &smsc911x_config, }, };

.config 파일에

CONFIG_SMSC911X=y

로 되어 있어야 합니다.
