[microblaze-uclinux] USB : Problem in porting C67x00 Driver to petalinux

[Childhood Hwang <childhood.hwang@xxxxxxxxx>]

I am tring to port C67x00 driver to petalinux right now. But I
can't make it work.
I saw there was some discussion before, and it seem's that those
discussions were the right thing  messing me.

I found the discussion in link: http://marc.info/?t=122849175200004&r=1&w=2

But there is no answer how to getover this, just that the problem was
in different status handling for older kernel.

I am quite newest to Linux.

I insert a kernel module that register the platform device for USB,
I think the interrupt works well.
Register code is like that,:

static struct resource c67x00_resources[] = {
       [0] = {
               .start  = 0x80800000,
               .end    = 0x8080ffff,
               .flags  = IORESOURCE_MEM,
       },
       [1] = {
               .start  = 0,
               .end    = 0,
               .flags  = IORESOURCE_IRQ,
       },
};

static struct c67x00_platform_data c67x00_data = {
       .sie_config             = C67X00_SIE1_HOST | C67X00_SIE2_HOST,
       .hpi_regstep            = 0x02,
};

static struct platform_device c67x00_device = {
       .name                   = "c67x00",
       .id                     = -1,
       .num_resources          = ARRAY_SIZE(c67x00_resources),
       .resource               = c67x00_resources,
       .dev.platform_data      = &c67x00_data,
};

static int __init c67x00_device_reg_init(void)
{
       /* printk("<1>Hello module world.\n");
       printk("<1>Module parameters were (0x%08x) and \"%s\"\n", myint,
              mystr); */
       printk("======== Call : c67x00_device_reg_init() ========\n");

       /* A non 0 return means init_module failed; module can't be loaded. */
       return platform_device_register(&c67x00_device);
}


static void __exit c67x00_device_reg_exit(void)
{
       printk(KERN_ALERT "======== Goodbye c67x00_device_reg_exit().
========\n");
       platform_device_unregister(&c67x00_device);
}

module_init(c67x00_device_reg_init);
module_exit(c67x00_device_reg_exit);


And the log list below:
