Re: [LinuxBIOS] [RFC][PATCH 2/2] x86_64: earlyprintk usb debug device support.

[Lu, Yinghai]

Eric,

Please check the version I modified for LinuxBIOS from your
usbdebug_direct.

Put the related info in
struct ehci_debug_info {
        void *ehci_base;
        void *ehci_op_base;
        void *ehci_debug_base;
        unsigned devnum;
        unsigned endpoint_out;
        unsigned endpoint_in;
    int inited;
};

So for CAR stage code, I could put it the range after stack and easy to
retrieve.
