The A64 DRAM controller is very similar to the H3 one,
so the code can be reused with some small changes.
This refactoring does not change the code size for the existing H3 part.
[Andre: rework from #ifdefs to using socid parameters in static
functions, minor fixes, merging in fixes from Jens]

sunxi: A64: do an RMR switch if started in AArch32 mode
The Allwinner A64 SoC starts execution in AArch32 mode, and both
the boot ROM and Allwinner's boot0 keep running in this mode.
So U-Boot gets entered in 32-bit, although we want it to run in AArch64.
By using a "magic" instruction, which happens to be an almost-NOP in
AArch64 and a branch in AArch32, we differentiate between being
entered in 64-bit or 32-bit mode.
If in 64-bit mode, we proceed with the branch to reset, but in 32-bit
mode we trigger an RMR write to bring the core into AArch64/EL3 and
re-enter U-Boot at CONFIG_SYS_TEXT_BASE.
This allows a 64-bit U-Boot to be both entered in 32 and 64-bit mode,
so we can use the same start code for the SPL and the U-Boot proper.
We use the existing custom header (boot0.h) functionality, but restrict
the existing boot0 header reservation to the non-SPL build now. A SPL
wouldn't need such header anyway. This allows to have both options
defined and lets us use one for the SPL and the other for U-Boot proper.
Also add arch/arm/mach-sunxi/rmr_switch.S, which contains the original
ARM assembly code and instructions how to re-generate the encoded
version.

ARM: boot0 hook: remove macro, include whole header file
For prepending some board specific header area to U-Boot images we
were so far including a header file with a macro definition containing
the actual header specification.
This works fine if there are just a few statements and if there is only
one alternative.
However adding more complex code quickly gets messy with this approach,
so let's just drop that intermediate macro and let the #include actually
insert the code directly.
This converts the callers and the callees, but doesn't change anything
at this point.

armv8: move reset branch into boot hook
The boot0 hook we have so far is applied _after_ the initial branch
to the "reset" entry point. An upcoming change requires even this
branch to be changed, so we apply the hook macro at the earliest
point, and have the branch in the hook file as well.
This is no functional change at this point, just refactoring to simplify
upcoming patches.

ARM: revive CONFIG_USE_ARCH_MEMCPY/MEMSET for UniPhier and Tegra
Commit be72591bcd64 ("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.

H3 SID controller has some bug, which makes the initial SID value at
SUNXI_SID_BASE wrong when boot.
Change the SID retrieve code to call the SID Controller directly on H3,
which can get the correct value, and also fix the SID value at
SUNXI_SID_BASE, so that it can be used by further operations.
