By moving some kirkwood files into a Marvell common directory, those files can be used by other Marvell platforms as well. The name mvebu is taken from the Linux kernel source tree. It has been chosen there to represent the SoC's from the Marvell EBU (Engineering Business Unit). Those SoC's currently are:

Armada 370/375/XP, Dove, mv78xx0, Kirkwood, Orion5x

This will be used by the upcoming Armada XP (MV78460) platform support.

These mbus functions are ported from Barebox. The Barebox version is ported from Linux. These functions will be first used by the upcoming Armada XP support. Later other Marvell SoC's will be adopted to use these functions as well (Kirkwood, Orion).

This patch adds support for the NETA ethernet controller which is integrated in the Marvell Armada XP SoC's. This port is based on the Linux driver which has been stripped of the in U-Boot unused portions.

Tested on the Marvell MV78460 eval board db-78460-bp.

Changes in v3: - Added Tested-by from Luka - Rebased on current top-of-tree (git ID a1263632)

Changes in v2: - Renamed target from db-78460-bp to db-mv784mp-gp as this matches the real eval board name

All those functions removed with this patch are not accessed at all. So lets remove them.

Add target to build it automatically upon "make" / MAKEALL. This can/should be set by board / cpu specific headers if a special U-Boot image is required for this SoC / board.

E.g. used by Marvell Armada XP to automatically build the u-boot.kwb target.

Changes in v3: None Changes in v2: - Rebased on latest U-Boot version already including the Kconfig support switch. - Removed patch "[PATCH v1 21/25] arm: kirkwood: Use mvebu new common mbus API" as this breaks Kirkwood booting. This needs to be resolved at some time, but I don't have access to a Kirkwood based board with JTAG BDI access to debug it right now. Till somebody fixes this issue, lets just remove it from this series for now. - Added basic support for the maxBCM MV78460 based board
