This device uses SDHCI driver, for eMMC and SD cards.
Trying bind the DW MMC driver with fdt node without all
required properties, causes printing an error.
This commit disables the DW MMC node.

After rework of code by:
commit: d952796 Exynos5: Use clock_get_periph_rate generic API
function get_mmc_clk() always returns -1 for Exynos 4.
This was caused by omitting, that SDHCI driver for Exynos 4,
calls get_mmc_clk(), with mmc device number as argument,
instead of pinmux peripheral id, like DW MMC driver for Exynos 5.
By this commit, the code directly calls a proper function
to get mmc clock for Exynos 4, without checking the peripheral id.
Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon).

The 7" Q8 tablet enclosure is used for a ton of slightly different cheap
chinese tablets. There are some differences in which accelerometer /
wifi is used, but other then that these are all the same from a u-boot /
kernel pov.
When we get to adding accelerometer support the plan is to add some kind
of autodetection and mangle the dt accordingly (likely using the new quirks
mechanism).
For now this is a non issue as we do not yet have accelerometer
support, and in the future, some sort of auto-detect is the way to go
as we cannot expect users to exactly know what is inside their tablet.
The dts files this commit adds are identical to the ones submitted
to the upstream kernel.

As reported by Simon Guinot, commit ade741b3
"arm: mvebu: Call timer_init early before PHY and DDR init" breaks
Kirkwood platforms. As the static variable "init_done" is not
available at that early boot time. This patch moves it to explicitly
to the data section, making it available at that time.

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.

This patch extends the misc_init_r() function on sunxi boards
to test for the presence of a suitable "sunxi" SPL header. If
found, and the loader ("fel" utility) provided a non-zero value
for the boot.scr address, then the corresponding environment
variable fel_scriptaddr gets set.
misc_init_r() also sets (or clears) the "fel_booted" variable depending
on the active boot device, using the same logic as spl_boot_device().
The goal is to provide sufficient information (within the U-Boot
environment) to make intelligent decisions on how to continue the boot
process, allowing specific customizations for the "FEL boot" case.

This patch follows up on a discussion of ways to improve support
for the sunxi FEL ("USB boot") mechanism, especially with regard
to boot scripts, see:
https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ
The idea is to convert the (currently unused) "pad" bytes in the
SPL header into an area where data can be passed to U-Boot. To
do this safely, we have to make sure that we're actually using
our "sunxi" flavor of the SPL, and not the Allwinner boot0.
The modified mksunxiboot introduces a special signature to the
SPL header in place of the "pub_head_size" field. This can be
used to reliably distinguish between compatible versions of sunxi
SPL and anything else (older variants or Allwinner's boot0).

The sunxi platform currently doesn't seem to make any use of the
asm/arch-sunxi/spl.h file. This patch moves some declarations from
tools/mksunxiboot.c into it.
This enables us to reuse those definitions when extending the

Use DM for the pl01x serial driver on hikey. Also allow UART0 or
UART3 to be chosen via Kconfig.
By default we now output to UART3 as the latest version of ATF outputs
to this UART. Also UART3 comes out on the LS connector, as opposed to
UART0 which goes to a unpopulated header.
As part of this change we also enable CONFIG_BOARD_EARLY_INIT_F and
call the pinmux configuration code for the UART. Before we were
relying on ATF having already configured the pin configuration.
NB: Upstream Linux kernel doesn't yet support UART3, so serial console
will still be output on UART0 when booting a upstream kernel.

Before this commit, the Kconfig menu in mach-uniphier only allowed us
to choose one SoC to be compiled. Each SoC has its own defconfig file
for the build-test coverage. Consequently, some defconfig files are
duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and
CONFIG_{SOC_NAME}=y.
Now, most of board-specific parameters have been moved to device trees,
so it makes sense to include init code of multiple SoCs into a single
image as long as the SoCs have similar architecture. In fact, some
SoCs of UniPhier family are very similar:
- PH1-LD4 and PH1-sLD8
- PH1-LD6b and ProXstream2 (will be added in the upcoming commit)
This commit will be helpful to merge some defconfig files for better
maintainability.

Currently, IECTRL is enabled after pin-mux settings for the low-level
debugging for PH1-LD4 and PH1-sLD8. While IECTRL is disabled, input
signals are pulled-down, i.e. glitch signal (Low to High transition)
problem occurs if pin-mux is set up first. As a result, one invalid
character is input to the UART block and the auto-boot counting is
terminated immediately.
The correct initialization procedure is:
[1] Enable IECTRL (if IECTRL exists for the pins)
[2] Set up pin-muxing
[3] Deassert the reset of the hardware block
Currently, the low-level debugging is working for PH1-sLD3 and
PH1-Pro4, but just in case, follow the sequence for all the SoCs.

In UniPhier SoCs before ProXstream2 and PH1-LD6b, two address spaces
0x00000000 - 0x0fffffff
0x40000000 - 0x4fffffff
are both mapped to the external bus (also called system bus),
so either was OK.
In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is
assigned for the serial NOR interface.
Going forward, use the latter for the external bus.

The "soc" node (this is simple-bus node) also needs the property
to bind the pinctrl node located under it.
I am collecting this U-Boot specific hack to the bottom of board
DTS rather than inserting "u-boot,dm-pre-reloc" into SoC DTSI.
My goal is to sync DTSI with Linux for easier maintenance.
