c72f4d4c2e ARM: uniphier: add PLL init code for LD11 SoC
- Initialize PLLs (SPL initializes only DPLL to save the precious
   SPL memory footprint)
 - Adjust CPLL/MPLL to the final tape-out frequency
 - Set the Cortex-A53 clock to the maximum frequency since it is
   running at 500MHz (SPLL/4) on startup

682e09ff9f ARM: uniphier: add PLL init code for LD20 SoC
Initialize the DPLL (PLL for DRAM) in SPL, and others in U-Boot
proper.  Split the common code into pll-base-ld20.c for easier
re-use.

fcc238baee ARM: uniphier: collect clock/PLL init code into a single directory
Now PLLs for DRAM controller are initialized in SPL, and the others
in U-Boot proper.  Setting up all of them in a single directory will
be helpful when we want to share code between SPL and U-Boot proper.

6a3e4274e4 ARM: uniphier: move PLL init code to U-Boot proper where possible
The PLL for the DRAM interface must be initialized in SPL, but the
others can be delayed until U-Boot proper.  Move them from SPL to
U-Boot proper to save the precious SPL memory footprint.

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

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.

cd0847fe63 ARM: uniphier: switch over to generic EHCI driver
The UniPhier EHCI driver (drivers/usb/host/ehci-uniphier.c) does
nothing special but set the base address and handle reset/clock.

Since commit 4feefdcfe9 ("usb: add clock support for generic EHCI"),
the generic one (drivers/usb/host/ehci-generic.c) can do those, too.

We no longer need to stick to the dedicated driver.

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.
