[PATCH RFC 00/11] introduce DPAA Ethernet driver

[Madalin Bucur]

This patch series introduces the Ethernet driver for the
Freescale QorIQ Data Path Acceleration Architecture (DPAA).
Together with the driver a managed version of alloc_percpu
is provided that simplifies the release of percpu memory.

The Freescale DPAA architecture consists in a series of
hardware blocks that support the Ethernet connectivity.
the Ethernet driver depends upon the Peripheral Access
Memory Unit (PAMU), Frame Manager (FMan), Queue Manager
(QMan), Buffer Manager (BMan). Drivers for these blocks
are currently in the kernel or in review.

The current set of RFC patches is meant to provide early
access to the codebase and also provide context and aid
the review of the FMan driver patches submitted by Igal
Liberman:

The DPAA Ethernet driver is the result of the collaborative
work of many individuals, to name a few:
 Andy Fleming
 Emil Medve
 Kumar Gala
 Ioana Radulescu
 Bogdan Hamciuc
 Madalin Bucur
 Cristian Sovaiala
 Marian Rotariu
 Andrei Pistirica
 Cristian Bercaru
 
The current patch set is the result of a sustained clean-up
and adaptation work on the QorIQ DPAA drivers released in
the open source Freescale SDK. The SDK drivers differ as they
offer support for advanced accelerations and other features
that are not upstreamable. The SDK Ethernet driver is based
on a different, non-upstreamable variant of the FMan driver.
The short term goal is to provide basic Ethernet support in
the vanilla kernel then to gradually increase the feature set. 

The SDK documentation and source code, documentation for the
DPAA hardware are available from the company website.
