e1b078e06c arm: mvebu: Update CBAR with SOC regs base
SMP-enabled Linux kernels read the CBAR register in CP15 to find
the address of the SCU registers.  After remapping internal
registers, also update the CBAR so the kernel can find them.

5730360efc arm: mvebu: Disable L2 cache before enabling d-cache
L2 cache may still be enabled by the BootROM. We need to first disable
it before enabling d-cache support.

2083db7a75 arm: mvebu: Remove "u-boot.kwb" CONFIG_BUILD_TARGET for non-SPL targets
By removing this default build target, the "u-boot.kwb" target is not
automatically generated. This fixes a temporary build error when using
out-of-tree builds, as buildman does per default (reported by Simon).

When the full SPL support is added for these targets with the DDR training
code, the "u-boot-spl.kwb" image will be generated automatically.

Users providing a special bin_hdr binary (binary.0) file can always add
this binary file and generate the full firmware image by issuing the
"make u-boot.kwb" command directly.

60b75324ea arm: mvebu: Add d-cache invalidate before enabling the d-cache
This solves some RX problems that have been seen, when using the
mvneta ethernet driver. The cache needs to be reset into a "clean"
state before using it.

e89bf8bcc9 arm: mvebu: Remove coherency configuration
We are not using the coherency feature in U-Boot at all. So lets remove
this configuration from the mbus driver.

cae9008f69 arm: mvebu: Change network init code to allow a more flexible setup
With the introduction of the Armada 38x support, its necessary to change
the mvneta ethernet driver init call from always 4 times to a
configurable value. Lets make this init call more flexible by moving
the actually used devices to the config header.

Additionally this patch takes care of the slightly different base
addresses for the ethernet controllers on A38x.

9c6d3b7b66 arm: mvebu: Add basic Armada 38x support
This patch adds support for the Marvell Armada 38x SoC family.

Supported peripherals are:
- UART
- Ethernet (mvneta)
- I2C
- SPI (including SPI NOR flash)

Tested on Marvell DB-88F6820-GP evaluation board.

Move arch/arm/include/asm/arch-armada-xp/*
     -> arch/arm/mach-mvebu/include/mach/*

Additionally the SYS_SOC is renamed from "armada-xp" to "mvebu". With this
change all these files can better be shared with other, newer Mavell
MVEBU SoC's. Like the upcoming Armada 38x support.

350b50eea3 arm: armada-xp: Move SoC sources to mach-mvebu
Move arch/arm/cpu/armv7armada-xp/* -> arch/arm/mach-mvebu/*

Since this platform will be extended to support other Marvell SoC's as
well, lets rename it directly to mvebu.

This will be used by the upcoming Armada 38x suport (A38x).
