bf0db8b82a arm: mvebu: Add support for MV78260
This patch adds support for the dual core Armada XP variant, the
MV78260. It has some minor differences to the 4-core MV78460,
e.g. only 12 serdes lanes.

c86d53fd88 arm: mvebu: Don't disable cache at startup on Armada XP at all
This patch leaces the cache configuration untouched for the AXP in the
setup done by the BootROM. Resulting in the cache still being enabled
at the startup of U-Boot. This leads to a slightly faster boot to the
U-Boot prompt (or Linux of course).

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.

Add functionality to correctly disable the L2 cache on the Armada XP

Without this, booting into Linux on ClearFog (A38x) results in a hangup
without any output on the serial console at all. Even with earlyprintk
enabled.

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.

When running on the AXP I sometimes noticed a strange behavior. As some
characters are not echoed on the U-Boot prompt. Not disabling the
lowlevel_init code, especially calling cpu_init_cp15() in the main
U-Boot seems to solve this issue.

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.

This patch now makes sure, no such runtime detection is used before
the internal registers are configured to the new location. After this,
the remaining cache cleanup is executed.

9c28d61c8e pci: mvebu: Add PCIe driver
This adds a PCI driver for the controllers found on Marvell MVEBU SoCs.

Besides the driver, this patch also removes the statically defined
PCI MBUS windows. As they are not needed anymore, since this PCIe
driver now creates the windows dynamically.

Tested on Armada XP db-mv784mp-gp eval board using an Intel E1000
PCIe card in all 3 PCIe slots. And on the Armada 38x db-88f6820-gp
eval board using this Intel E1000 PCIe card in the PCIe 0 slot.

This port was done in cooperation with Anton Schubert.

dee40d26d3 arm: mvebu: Enable USB EHCI support on Armada XP
This patch enables the USB EHCI support for the Marvell Armada XP (AXP)
SoCs. In compatism to the Armada 38x (A38x), the AXP needs to configure
the USB PLL and the USB PHY's specifically in U-Boot. The A38x has done
this already in the bin_hdr (SPL U-Boot). Without this, accessing the
controller registers in U-Boot or Linux will hang the CPU.

Additionally, the AXP uses a different USB EHCI base address. This
patch also takes care of this by runtime SoC detection in the Marvell
EHCI driver.

2b181b5b04 arm: mvebu: Flush caches and disable MMU only on A38x
Only with disabled MMU its possible to switch the base register address
on Armada 38x. Without this the SDRAM located at >= 0x4000.0000 is also
not accessible, as its still locked to cache.

So to fully release / unlock this area from cache, we need to first
flush all caches, then disable the MMU and disable the L2 cache.

On Armada XP this does not seem to be needed. Even worse, with this
code added, I sometimes see strange input charactes loss from the
console.
