[PATCH 1/3] Freescale QE UCC gigabit ethernet driver

Li Yang-r58472 LeoLi at freescale.com
Thu Jul 6 22:02:22 EST 2006


This is a re-submission of the patch after some fix. First version of
the patch may be blocked by the list due to size problem.

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.

The patch is cut into 3 pieces for size reason.
