Linux3.6.7在OK6410平台的移植（十）USB

1.mach-ok6410.c文件中增加如下内容：

#include

#include
#include

#ifdef CONFIG_USB_SUPPORT
void s3c_hsotg_phy_config(int enable) {
u32 val;

if (enable) {
__raw_writel(0x0, S3C_PHYPWR); /* Power up */

val = __raw_readl(S3C_PHYCLK);
val &= ~S3C_PHYCLK_CLKSEL_MASK;
__raw_writel(val, S3C_PHYCLK);

__raw_writel(0x1, S3C_RSTCON);
udelay(5);
__raw_writel(0x0, S3C_RSTCON); /* Finish the reset */
udelay(5);
} else {
__raw_writel(0x19, S3C_PHYPWR); /* Power down */
}
}
EXPORT_SYMBOL(s3c_hsotg_phy_config);

#endif

并在static void __init ok6410_machine_init(void)函数中增加s3c_hsotg_phy_config（1）；

2.linux 3.6.7/arch/arm/plat-samsung/devs.c文件中void __init s3c_hsotg_set_platdata(struct s3c_hsotg_plat *pd)屏蔽掉s5p_usb_phy_init，s5p_usb_phy_exit。

3.内核配置：

 [*] USB announce new devices  
 <*> OHCI HCD support  
 <*> USB Mass Storage support   

系统启动后插入U盘，显示如下信息：
