From 477434c63c2ea5baa5c6c4e43500786f436511ff Mon Sep 17 00:00:00 2001 From: Sergei Poselenov Date: Thu, 22 May 2008 01:15:53 +0200 Subject: [PATCH] USB: add support for multiple PCI OHCI controllers Add new configuration variable CONFIG_PCI_OHCI_DEVNO. In case of several PCI USB controllers on a board this variable specifys which controller to use. Also add USB support for sokrates board. See doc/README.generic_usb_ohci for details.
