45a68fe267 mmc: move some SDHCI related options to Kconfig
While I moved the options, I also renamed them so that they are all
prefixed with MMC_SDHCI_.

This commit was created in the following steps.

[1] Rename with the following command
find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '
s/CONFIG_MMC_SDMA/CONFIG_MMC_SDHCI_SDMA/g

s/CONFIG_S5P_SDHCI/CONFIG_MMC_SDHCI_S5P/g
s/CONFIG_SPEAR_SDHCI/CONFIG_MMC_SDHCI_SPEAR/g
'

[2] create the Kconfig entries in drivers/mmc/Kconfig

[3] Move the options by the following command
tools/moveconfig.py -y MMC_SDHCI_SDMA MMC_SDHCI_BCM2835 \
MMC_SDHCI_KONA MMC_SDHCI_MV MMC_SDHCI_S5P MMC_SDHCI_SPEAR

[4] Sort drivers/mmc/Makefile for readability

d7b4731efd arm: mvebu: Add support for NAND interface on A-38x
The NAND interface on the Armada-38x series is similar to that on the
Armada-XP. The key difference is that the NAND ECC clock ratio is
provided via the DFX Server registers instead of the Core Clock.

09e89ab4af arm: mvebu: Add basic support for the Marvell Armada 375 SoC
This patch adds basic support for the Armada 375. Please note that
currently the SerDes and DDR3 init code for the A375 is not
included / enabled. This will be done in a later, follow-up patch.

Right now, this A375 mainline U-Boot can only be used by chainloading
it via the original Marvell U-Boot. This can be done via this
command:

=> tftpboot 00800000 a375/u-boot-dtb.bin;go 00800000

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.

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.

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.

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

So to fully release / unlock this area from cache, we need to first

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
