[package] base-files: update sysctl.conf for modern kernels
[openwrt.git] / target / linux / brcm63xx / patches-2.6.37 / 007-usb-ohci-support.patch
1 The bcm63xx SOC has an integrated OHCI controller, this patch adds
2 platform device registration and change board code to register ohci
3 device when necessary.
