Subject: [v2 0/9] dpaa_eth: Add the Freescale DPAA Ethernet driver

This patch series adds the Ethernet driver for the Freescale
QorIQ Data Path Acceleration Architecture (DPAA).

This version includes changes following the feedback received
on previous versions from Eric Dumazet, Bob Cochran, Joe Perches,
Paul Bolle, Joakim Tjernlund, Scott Wood, David Miller - thanks!

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 following drivers that are currently in the Linux
kernel or in review:
 - Peripheral Access Memory Unit (PAMU)
    drivers/iommu/fsl_*
 - Frame Manager (FMan)
    drivers/net/ethernet/freescale/fman
 - Queue Manager (QMan), Buffer Manager (BMan)
    drivers/soc/fsl/qbman

The latest FMan driver patches were submitted by Igal Liberman:
https://patchwork.ozlabs.org/project/netdev/list/?submitter=64715&state=*&q=[v4,

The latest Q/BMan drivers were submitted by Roy Pledge:
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?submitter=66331&state=*

Changes from v1:
 - bpool level Kconfig options removed
 - print format using pr_fmt, cleaned up prints
 - __hot/__cold removed
 - gratuitous unlikely() removed
 - code style aligned, consistent spacing for declarations
 - comment formatting

The complete patch set based on the v4.2-rc5 kernel can be found
in the public git http://git.freescale.com/git/cgit.cgi/ppc/upstream/linux.git
under the tag ldup_public_git_20150805:
http://git.freescale.com/git/cgit.cgi/ppc/upstream/linux.git/log/?h=ldup_public_git_20150805

There is one patch that needs to be applied to u-boot to align it
to the latest device tree binding document specification used by
the FMan driver. The patch is under the ldup_public_git_20150410
tag in the public git at:
http://git.freescale.com/git/cgit.cgi/ppc/upstream/u-boot.git/log/?h=ldup_public_git_20150410
