On the A64 we usually boot with ATF running in EL3. ATF as it is available
today resides in the first 16MB of RAM. So we should make sure we reserve
that space in our memory maps.

The Pine64+ is a system based on the Allwinner A64 SoC. It is capable of
running AArch64 code and thus is the first of its kind for the sunxi target.
This patch adds a defconfig and device tree chunks for it.

The Allwinner A64 SoC is used in the Pine64. This patch adds
all bits necessary to compile U-Boot for it running in AArch64
mode.
Unfortunately SPL is not ready yet due to legal problems, so
we need to boot using the binary boot0 for now.

Some parts of the sunxi code cast explicitly between u32 values and pointers.
This is not a problem in practice, because all 64bit SoCs today only use the
lower 32 bits for their phyical address space. But we need to make sure that
the compiler is sure this is not an accident as well.

Upcoming new pinctrl drivers for PH1-LD11 and PH-LD20 support input
signal gating for each pin. (While, existing ones only support it

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
The core part of the UniPhier pinctrl driver needs to support a new
capability for upcoming UniPhier ARMv8 SoCs. This sometimes happens
because pinctrl drivers include really SoC-specific stuff.
This commit intends to tidy up SoC-specific parameters of the existing
drivers before adding new ones. Having flags would be better than
adding new members every time a new SoC-specific capability comes up.
At this time, there is one flag, UNIPHIER_PINCTRL_CAPS_DBGMUX_SEPARATE.
This capability (I'd say rather quirk) was added for PH1-Pro4 and
PH1-Pro5 as requirement from our customer. For those SoCs, one pin-mux
setting is controlled by the combination of two separate registers; the
LSB bits at register offset (8 * N) and the MSB bits at (8 * N + 4).
Because it is impossible to update two separate registers atomically,
the LOAD_PINCTRL register should be set in order to make the pin-mux
settings really effective.

This patch introduces CONFIG_RTL8211X_PHY_FORCE_MASTER. If this
define is set, RTL8211x PHYs (except for the RTL8211F) will have their
1000BASE-T master/slave autonegotiation disabled and forced to master
mode.
This is helpful for PHYs like the RTL8211C which produce unstable links
in slave mode. Such problems have been found on the A20-Olimex-SOM-EVB
and A20-OLinuXino-Lime2.
There is no proper way to identify affected PHYs in software as the
RTL8211C shares its UID with the RTL8211B. Thus, this fix requires
the introduction of an #ifdef.
