83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

bef4b024e9 ARM: uniphier: move pin-mux code into pin_init function
The code in uniphier_sld3_sbc_init() is pin-muxing, so it would
be a better fit in uniphier_sld3_early_pin_init().

5eb4150e84 ARM: uniphier: allow to use System Bus for ROM boot mode of PH1-LD20
The System Bus is not available by default on the ROM boot mode of
PH1-LD20.  To use devices connected to the System Bus, such as the
Micro Support Card, it is necessary to set up pin-muxing and some
System Bus Controller register.

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.

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.

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.
