Thank you very much,

Following your instruction, I did
int usb_board_init(void)
{
    printf("usb_board_init\n");

    outw(0x18, STBCR3);
    outw(0x18, SRSTR);
    udelay(10);

    outw(0x28, EXCPGCR);
    udelay(10);
	
    outw(0x00, STBCR3);
    outw(0x00, SRSTR);
    return 0;
}

I couldn't see this register "STCBR3 ", I only saw STBCR3. Is it correct?

But UBoot didn't work, Would you please tell me more detail ?
