[PATCH RFC 00/10] introduce DPAA Ethernet driver

[Madalin Bucur <madalin.bucur@freescale.com>]

This is the second version of a patch series that adds
the Ethernet driver for the Freescale QorIQ Data Path
Acceleration Architecture (DPAA).

This second version includes the changes requested by
Kumar Gala. The PM ops patch was removed as the
supporting FMan driver code was de-featured from the
first submission of the driver to reduce the review
effort. 

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 latest FMan driver patches submitted
by Igal Liberman:

[RFC,v2,12/12] soc/fman: Add FMan MAC driver

These patches rely also on the Q/BMan drivers submitted by
Emil Medve:

[RFC,v3,10/10] fsl_qman: Add HOTPLUG_CPU support
[RFC,v3,09/10] fsl_bman: Add HOTPLUG_CPU support
[RFC,v3,08/10] fsl_qman: Add debugfs support
[RFC,v3,07/10] fsl_bman: Add debugfs support
[RFC,v3,06/10] fsl_qman: Add self-tester
[RFC,v3,05/10] fsl_bman: Add self-tester
[RFC,v3,04/10] powerpc/mpc85xx: Add platform support for the Freescale DPAA QMan
[RFC,v3,03/10] powerpc/mpc85xx: Add platform support for the Freescale DPAA BMan
[RFC,v3,02/10] fsl_qman: Add drivers for the Freescale DPAA QMan
[RFC,v3,01/10] fsl_bman: Add drivers for the Freescale DPAA BMan

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.
