5b66006646 ARM: uniphier: rename function names ph1_* to uniphier_*
Eliminate the "ph1"_ prefixes from function names because "uniphier_"
describes the SoC familiy better.

d5cf32977f ARM: uniphier: support Debug UART
For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it.  Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.

This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.

5d0607c58c ARM: uniphier: refactor SBC init code
There is a bunch of duplication in the System Bus Controller init
code.  Roughly, there are two types in the SBC mode:  Adress/Data
Multiplex Mode and Save Pins Mode.  Consolidate per-SoC functions
into the two, plus per-SoC optional init code.

ea65c98050 ARM: uniphier: drop PH1- prefix from CONFIG options and file names
The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too
long.  It would not hurt to drop "PH1_" because "UNIPHIER_" already
well specifies the SoC family.  Also, rename files for consistency.

15607d0d94 ARM: uniphier: add DRAM init code for ProXstream2/PH1-LD6b
As mentioned in the log of commit 019df879a9 (ARM: uniphier: add
ProXstream2 and PH1-LD6b support), the DRAM init code was missing
for a long time.  Finally, here it is.  SPL works now.

107b3fb484 ARM: uniphier: move headers out of include/mach directory
These headers are only included locally in arch/arm/mach-uniphier/.
There is no reason to export them by putting in the mach/ directory.

Move "gd->fdt_blob" from the caller to the callee so that this
function can be used more easily.

da58dec866 Various Makefiles: Add SPDX-License-Identifier tags
After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one.  This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.

U-Boot proper should work.

323d1f9d5b ARM: uniphier: allow to enable multiple SoCs
Before this commit, the Kconfig menu in mach-uniphier only allowed us
to choose one SoC to be compiled.  Each SoC has its own defconfig file
for the build-test coverage.  Consequently, some defconfig files are
duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and
CONFIG_{SOC_NAME}=y.

Now, most of board-specific parameters have been moved to device trees,
so it makes sense to include init code of multiple SoCs into a single
image as long as the SoCs have similar architecture.  In fact, some
SoCs of UniPhier family are very similar:
 - PH1-LD4 and PH1-sLD8
 - PH1-LD6b and ProXstream2 (will be added in the upcoming commit)

This commit will be helpful to merge some defconfig files for better
maintainability.
