If the system is running PSCI firmware, the System Reset function
(func ID: 0x80000009) is supposed to be handled by PSCI, that is,
the SoC/board specific reset implementation should be moved to PSCI.
U-Boot should call the PSCI service according to the arm-smccc
manner.
The arm-smccc is supported on ARMv7 or later. Especially, ARMv8
generation SoCs are likely to run ARM Trusted Firmware BL31. In
this case, U-Boot is a non-secure world boot loader, so it should
not be able to reset the system directly.

driver is needed.
Add support for timer for Aspeed ast2400/ast2500 devices.
The driver actually controls several devices, but because all devices
share the same Control Register, it is somewhat difficult to completely
decouple them. Since only one timer is needed at the moment, this should
be OK. The timer uses fixed clock, so does not rely on a clock driver.

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.

We have long had available optimized versions of the memset and memcpy
functions that are borrowed from the Linux kernel. We should use these
in normal conditions as the speed wins in many workflows outweigh the
relatively minor size increase. However, we have a number of places
where we're simply too close to size limits in SPL and must be able to
make the size vs performance trade-off in those cases.

Commit be72591bcd ("Kconfig: Move USE_ARCH_MEMCPY/MEMSET to
Kconfig") is misconversion.
The original logic in include/configs/uniphier.h was as follows:
#if !defined(CONFIG_SPL_BUILD) && !defined(CONFIG_ARM64)
#define CONFIG_USE_ARCH_MEMSET
#define CONFIG_USE_ARCH_MEMCPY
#endif
This means those configs were enabled when building U-Boot proper,
but disabled when building SPL. Likewise for Tegra.
Now "depends on !SPL" prevents any boards with SPL support
from reaching these options. This changed the behavior for
UniPhier and Tegra SoC family.
Please notice these two options only control the U-Boot proper
build. As you see arch/arm/Makefile, ARM-specific memset/memcpy
are never compiled for SPL. So, __HAVE_ARCH_MEMCPY/MEMSET should
not set for SPL.

Valid Altera SoCFPGA preloader image must contain special data at
offsets 0x40, 0x44, 0x48 and valid instructions at address 0x4c or
0x50. These addresses are by default used by U-Boot's vector table
and a piece of reset handler, thus a valid preloader corrupts those
addresses slightly. While this works most of the time, this can and
does prevent the board from rebooting sometimes and triggering this
issue may even depend on compiler.
The problem is that when SoCFPGA performs warm reset, it checks the
addresses 0x40..0x4b in SRAM for a valid preloader signature and
header checksum. If those are found, it jumps to address 0x4c or
0x50 (this is unclear). These addresses are populated by the first
few instructions of arch/arm/cpu/armv7/start.S:
ffff0040 <data_abort>:
ffff0040: ebfffffe bl ffff0040 <data_abort>
ffff0044 <reset>:
ffff0044: ea000012 b ffff0094 <save_boot_params>
ffff0048 <save_boot_params_ret>:
ffff0048: e10f0000 mrs r0, CPSR
ffff004c: e200101f and r1, r0, #31
ffff0050: e331001a teq r1, #26
Without this patch, the CPU will enter the code at 0xffff004c or
0xffff0050 , at which point the value of r0 and r1 registers is
undefined. Moreover, jumping directly to the preloader entry point
at address 0xffff0000 will also fail, because address 0xffff004.
is invalid and contains the preloader magic.
Add BOOT0 hook which reserves the area at offset 0x40..0x5f and
populates offset 0x50 with jump to the entry point. This way, the
preloader signature is stored in reserved space and can not corrupt
the SPL code.
