commit 92cd6bc1170f57eb5a2adb20dd603041eed9ddf4 Author: Anton Kochkov anton.kochkov@gmail.com Date: Thu Jun 28 08:30:15 2012 +0400
libpayload: add controller type in usbdev_hc
Add controller type (UHCI, OHCI, EHCI or XHCI) into usbdev_hc (hci_t) struct, so now we know which type selected controller have. It needed to access controller specific data, if access usb tree outside of libpayload (e.g. in payload intself)
