[PATCH] Freescale QE UCC gigabit ethernet driver
QE(QUICC Engine) is a new generation communication coprocessor, which can
be found on some of the latest Freescale PowerQUICC CPUs(e.g. MPC8360).
The UCC(Unified Communications Controller) module of QE can work as gigabit
Ethernet device. This patch provides driver for the device.
