arm64: booti: allow to place kernel image anywhere in physical memory
At first, the ARM64 Linux booting requirement recommended that the
kernel image be placed text_offset bytes from 2MB aligned base near
the start of usable system RAM because memory below that base address
was unusable at that time.
This requirement was relaxed by Linux commit a7f8de168ace ("arm64:
allow kernel Image to be loaded anywhere in physical memory").
Since then, the bit 3 of the flags field indicates the tolerance
of the kernel physical placement. If this bit is set, the 2MB
aligned base may be anywhere in physical memory. For details, see
Documentation/arm64/booting.txt of Linux.
The booti command should be also relaxed. If the bit 3 is set,
images->ep is respected, and the image is placed at the nearest
bootable location. Otherwise, it is relocated to the start of the
system RAM to keep the original behavior.
Another wrinkle we need to take care of is the unknown endianness of
text_offset for a kernel older than commit a2c1d73b94ed (i.e. v3.16).
We can detect this based on the image_size field. If the field is
zero, just use a fixed offset 0x80000.

it is marked in an efuse register. If the register is fused,
the boot code should compensate for the DRAM clock duty error.

ARM: uniphier: rework spl_boot_device() and related code
The current implementation has ugly switch statements here and there,
and duplicates similar code. Rework it using table lookups for SoC
data and reduce code duplication.

ARM: uniphier: move spl_boot_mode() to a separate file
The spl_boot_mode() is unrelated to the other code in this file.
Besides, this function is only called from common/spl/spl_mmc.c,
so it is reasonable to guard with CONFIG_SPL_MMC_SUPPORT.

ARM: uniphier: move MMC code to a separate file
Currently, arch/arm/mach-uniphier/boot-mode/boot-mode.c is messed up
with unrelated code; there is no reason why the "mmcsetn" command
must be placed in this file.
Split out the MMC code into arch/arm/mach-uniphier/mmc-first-dev.c.

ARM: dts: uniphier: drop u-boot, dm-pre-reloc from system-bus pinctrl node
Since commit 26b09c022ab6 ("ARM: uniphier: move SBC and Support Card
init code to U-Boot proper"), SPL does not need pin-mux settings for
the System Bus.

ARM: uniphier: rename second stage loader name
For the memory footprint reason, the Boot ROM can not load the ARM
Trusted Firmware BL1 directly when Trusted Board Boot is enabled.
The second stage loader is Socionext's own firmware, so rename it
for clarification.

pinctrl: uniphier: support pin configuration
Support the following DT properties:
"bias-disable"
"bias-pull-up"
"bias-pull-down"
"bias-pull-pin-default"
"input-enable"
"input-disable"
My main motivation is to support pull up/down biasing. For Pro5 and
later SoCs, the pupdctrl register number is the same as the pinmux
number, so this feature can be supported without having big pin
tables.
