81e33f4b65 arm: mvebu: Move SoC selection (A38X vs AXP) into Kconfig
Until now, the SoC selection for the ARCH_MVEBU platforms has been done
in the config header. Using CONFIG_ARMADA_XP in a non-clear way. As
it needed to get selected for AXP and A38x based boards. This patch
now changes this to move the SoC selection to Kconfig. And also
uses CONFIG_ARCH_MVEBU as a common define for both AXP and A38x.
This makes things a bit clearer - especially for new board additions.

Additionally the defines CONFIG_SYS_MVEBU_DDR_AXP and
CONFIG_SYS_MVEBU_DDR_A38X are replaced with the already available
CONFIG_ARMADA_38X and CONFIG_ARMADA_XP.

And CONFIG_DDR3 is removed, as its not referenced anywhere.

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.

169789dcb9 sata: Add SATA driver with DMA support for Marvell Kirkwood and Armada XP
This patch adds a new SATA driver for the Marvell Kirkwood and Armada
370 / XP SoC's.

This driver supports the SATA controller of some Mavell SoC's.
Here a (most likely incomplete) list of the supported SoC's:
- Kirkwood
- Armada 370
- Armada XP

This driver implementation is an alternative to the already available
driver via the "ide" commands interface (drivers/block/mvsata_ide.c).
But this driver only supports PIO mode and as this new driver also
supports transfer via DMA, its much faster.

Please note, that the newer SoC's (e.g. Armada 38x) are not supported
by this driver. As they have an AHCI compatible SATA controller
integrated.

The original version of this driver was sent by Tor Krill to the U-Boot
list a few years ago. Here the link:

http://lists.denx.de/pipermail/u-boot/2010-June/073147.html

Changes by Stefan:
- Coding-style cleanup
- Support for Armada XP added
- MBUS window setup added
- D-cache flush and invalidation added - works with dcache enabled on
  Armada XP
- Removed mdelay() from ata_wait_register() and add timer based timeout
  detection to speed up the transfer

0299c90f39 arm: mvebu: Add SolidRun ClearFog Armada 38x initial support
This patch adds basic support for the SolidRun ClearFog Armada 38x based
board to mainline U-Boot. Supported interfaces / devices are:
- DDR3
- UART
- MMC
- Ethernet port 0 (connected to dedicated PHY)
- I2C

The included DT source was taken from Russell King's ftp server:
http://www.home.arm.linux.org.uk/~rmk/clearfog/

With only minor modifications, like the addition of some aliases and the
"u-boot,dm-pre-reloc" property.

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.

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:

   arch/arm/cpu/u-boot-spl.lds

This common linker script already handles all special cases. No need
to reinvent the wheel for MVEBU here.

20e072f374 image: check "bootm_low" and "bootm_size" if "initrd_high" is missing
To boot Linux, we should prevent Initramdisk and FDT from going too
high.

Currently, boot_relocate_fdt() checks "fdt_high" environment first,
and then falls back to getenv_bootm_mapsize() + getenv_bootm_low()
if "fdt_high" is missing.

On the other hand, boot_ramdisk_high() only checks "initrd_high" to
get the address limit for the Initramdisk.  We also want to let this
case fall back to getenv_bootm_mapsize() + getenv_bootm_low().
