    usbdebug: Quirk for board aopen/dxplplusu
    
    This ancient board with Intel e7505 invalidates cache while it does HW
    scrubbing for ECC in romstage. This breaks usbdebug console and prevents
    system from booting.
    
    If both EARLY_CONSOLE and USBDEBUG are selected, skip ECC scrubbing under
    these rare conditions to boot system.
