b6acb5f1d9 mmc: Add Marvell Xenon SDHCI controller driver
This driver implementes platform specific code for the Xenon SDHCI
controller which is integrated in the Marvell MVEBU Armada 37xx and
Armada 7k / 8K SoCs.

History:
This driver is ported from the Marvell U-Boot version 2015.01 which is
written by Victor Gu <xigu@marvell.com> with minor changes ported from
the Linux driver which is written by Ziji Hu <huziji@marvell.com>.

210841c690 mmc: sdhci: Add support for optional controller specific set_ios_post()
Some SDHCI drivers might need to do some special controller configuration
after the common clock set_ios() function has been called (speed / width
configuration). This patch adds a call to the newly created function
set_ios_port() when its configured in the host driver.

This will be used by the Xenon SDHCI controller driver used on the
Marvell Armada 3700 and 7k/8k ARM64 SoCs.

899fb9e352 mmc: sdhci: Clear SDHCI_CLOCK_CONTROL before configuring the new value
This patch completely clears the SDHCI_CLOCK_CONTROL register before the
new value is configured instead of just clearing the 2 bits
SDHCI_CLOCK_CARD_EN and SDHCI_CLOCK_INT_EN. Without this change, some
clock configurations will lead to the "Internal clock never stabilised."
error message on the Xenon SDHCI controller used on the Marvell Armada
3700 and 7k/8k ARM64 SoCs.

The Linux SDHCI core driver also writes 0 to this register before
the new value is configured. So this patch simplifies the driver a bit
and brings the U-Boot driver more in-line with the Linux one.

distinguishes between base clock (max_clk) of the host controller and maximum

the platform to constrain the peripheral interface.

561ca649a8 ARM: uniphier: make SPL optional for ARVv8 SoCs
We may want to run different firmware before running U-Boot.  For
example, ARM Trusted Firmware runs before U-Boot, making U-Boot
a non-secure world boot loader.  In this case, the SoC might be
initialized there, which enables us to skip SPL entirely.

This commit removes "select SPL" to make it configurable.  This
also enables the Multi SoC support for the UniPhier ARMv8 SoCs.
(CONFIG_ARCH_UNIPHIER_V8_MULTI)  Thanks to the driver model and
Device Tree, the U-Boot proper part is now written in a generic way.
The board/SoC parameters reside in DT.  The Multi SoC support
increases the memory footprint a bit, but the U-Boot proper does
not have strict memory constraint.  This will mitigate the per-SoC
(sometimes per-board) defconfig burden.

8c9bfc47ed meson: misc_init_r is board-specific
Move it from meson-gxbb-common.h to odroid-c2.h to allow new boards not

c67c8c604b board_init.c: Always use memset()
We can make the code read more easily here by simply using memset()
always as when we don't have an optimized version of the function we
will still have a version of this function around anyhow.
