Add functionality to correctly disable the L2 cache on the Armada XP
and 38x platforms.
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.

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.

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.

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 adds full DM support to the SPL on MVEBU. Currently
only serial is supported. Other drivers will follow.
This patch also adds the necessary config values for the DEBUG UART
to the MVEBU defconfig files. This came in handy while implementing
this DM support.
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.

since:
commit: f05ad9ba "Add a way to skip relocation"
tqm5200s board fails to boot. Reason is that
board_init_f has a function parameter bootflag,
which is not setup in
in arch/powerpc/cpu/mpc5xxx/start.S _start
So board_init_f gets a undefined bootflag,
currently the gd pointer address. Unfortunately
this address sets the GD_FLG_SKIP_RELOC bit,
so u-boot code gets not relocated and u-boot
does not boot ...
Init bootflag with 0, and tqm5200 boots fine again.

When we want to boot Linux with a DTB file downloaded from a TFTP
server or somewhere, we need to know the file name to be downloaded.
Assume the U-Boot configuration is shared among some similar boards.
If they are similar enough, the difference only appears in device
trees. The build procedure would be like this:
- Board A: make foo_common_defconfig && make DEVICE_TREE=foo_board_a
- Board B: make foo_common_defconfig && make DEVICE_TREE=foo_board_b
- Board C: make foo_common_defconfig && make DEVICE_TREE=foo_board_c
In this case, the U-Boot image contains nothing about the DTB file name
it is running with. (CONFIG_DEFAULT_DEVICE_TREE is not helpful for this
purpose because it is painful to change it from "make menuconfig" for
each board.)
This commit allows to lookup the DTB file name based on the compatible
string and set it to "fdt_file" environment. Then "tftpboot $fdt_file"
will download the file we want.
