commit 8b5decaa195a87fad4c329b70ee073b1e854fec1 Author: Tobias Diedrich ranma+openocd@tdiedrich.de Date: Sun Feb 12 22:58:37 2017 +0100
southbridge/intel/bd82x6x: Use correct EHCI address for USBDEBUG
The bd82x6x hardcoded EHCI bar adresses (0xe8000[04]00) don't match the CONFIG_EHCI_BAR default of 0xfef00000.
This copies the defines from southbridge/intel/lynxpoint/early_usb.c so that the early EHCI bar setup is using CONFIG_EHCI_BAR and CONFIG_USBDEBUG_HCD_INDEX to determine the correct bar addresses.
