This patch leaces the cache configuration untouched for the AXP in the

f4e6ec7dc6 arm: mvebu: Don't call arch_cpu_init() from SPL at all
This patch removes the call to arch_cpu_init() in the SPL U-Boot version.
As SPL does not need all the configuration done in this function. And
also does not need the reconfiguration of the internal register
address to 0xf1000000. This will be done by the main U-Boot later on.

This also fixes a problem with the timer not beeing initialized on AXP,
as needed for the mdelay in the setup_usb_phys(). This will now only
be called once in main U-Boot.

3e5ce7ceeb arm: mvebu: Enable L2 cache on Armada XP
Until now, the L2 cache was never enabled again in U-Boot. To get
even better performance (bootup time), lets enable the L2 cache
in U-Boot. This code was taken from the Linux kernel.

A performance gain was measured on the DB-MV784MP-GP board by testing
with tftpboot and sata commands.

This patch also cleans up the L2 cache related code. And makes sure that
the L2 cache is only disabled once.

Please note that A38x still runs with L2 cache disabled. And needs
to be enabled for this SoC in a separate patch if needed or desired.

e3b9c98a23 net: mvneta: Convert to driver model
Update this driver to support driver model. As all MVEBU boards using
this driver are converted with this patch, the non-driver-model code
can be removed completely. This is also the reason why this patch
is quite big and includes a) the driver change and b) the
platform change. As its not git-bisect save otherwise.

With this conversion, some parameters are now extracted from the
DT instread of using the config header defines. The supported
properties right now are:

PHY-mode ("phy-mode") and PHY-address ("reg").

The base addresses for the ethernet controllers can be removed from
the header files as well.

Please note that this patch also removes the E1000 network driver
from some MVEBU config headers. This is necessary, as with DM_ETH
configured and the e1000 driver enabled, the PCI driver also needs
to support DM. But the MVEBU PCI(e) driver still needs to get
ported to DM. When this is done, the E1000 driver can be enabled
again.

only serial is supported. Other drivers will follow.

This patch also adds the necessary config values for the DEBUG UART

Additionally, the mvebu specific SPL linker script is removed and
this common one is used instead:

cefd764222 arm: mvebu: Fix internal register config on A38x
Currently booting on A38x is broken. As the current code tries to detect
the SoC family to disable the MMU for the A38x at runtime. But before the
internal registers are switched to the new location (0xf100.0000), this
runtime detection does not work. As all macros / defines are already
assigned to the new location at 0xf100.0000. But the registers are sill
mapped to the default location at 0xd000.0000.

the internal registers are configured to the new location. After this,
the remaining cache cleanup is executed.

8ed43b966c arm: mvebu: Add SPL SDIO/MMC boot support
This patch adds basic SDIO/MMC booting support to MVEBU SoC's. Since
I don't know of a way to test the boot-device upon runtime, this patch
hardcodes the spl_boot_device instead.

Tested on Marvell DB-88F6820-GP board.

ff9112df8b arm: mvebu: drivers/ddr: Move Armada XP DDR init code into new directory
With the upcoming addition of the Armada 38x DDR support, which is not
compatible to the Armada XP DDR init code, we need to introduce a new
directory infrastructure. To support multiple Marvell DDR controller.

This will be the new structure:

     drivers/ddr/marvell/axp
     Supporting Armada XP (AXP) devices (and perhaps Armada 370)

     drivers/ddr/marvell/a38x
     Supporting Armada 38x devices (and perhaps Armada 39x)

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.
