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.

As part of my usual round of build testing, output about missing
MAINTAINERS information was not logged, and thus often overlooked.
Correct that mistake by ensuring that I log the output of
genboardscfg.py every time. As part of that, address a number of
missing MAINTAINERS entires. In the case of a missing file, I have put
the original submitter down. In the rest of the cases I have added the
config (and sometimes relevant header file) to the existing set of file
globs.

This patch adds the necessary OF alias for the UDC node, which let's
the code locate the DWC2 UDC base address in OF instead of hard-coding
it into the U-Boot binary. The code is adjusted to use the address from
OF instead of the hard-coded one. Finally, the hard-coded address is
removed and USB DM support is enabled.

Now that we're actually converting the QTS-generated header files,
we can even adjust their data types. A good candidate for this is
the pinmux table, where each entry can have value in the range of
0..3, but each element is declared as unsigned long. By changing
the type to u8, we can save over 600 Bytes from the SPL, so do it.
This patch also constifies the array.

The board/altera/socfpga directory is not a generic SoCFPGA machine
anymore, but instead it represents the Altera SoCDK board. To make
matters more complicated, it represents both CycloneV and ArriaV
variant.
On the other hand, nowadays, the content of this board directory is
mostly comprised of QTS-generated header files, while all the generic
code is in arch/arm/mach-socfpga already.
Thus, this patch splits the board/altera/socfpga into a separate
board directory for ArriaV SoCDK and CycloneV SoCDK, so that each
can be populated with the correct QTS-generated header files for
that particular board.

Implement new accessor, sysmgr_get_pinmux_table(), used to obtain pinmux
table and it's size from the QTS-generated pinmux_config.c. The target
here is again to get rid of poluting global namespace by including the
pinmux_config.h into it.
Furthermore, the pinmux_config.h declares some CONFIG_HPS_* macros,
which are explicitly useless to us in U-Boot. Instead, U-Boot does
use DT to detect exactly these configuration options. This patch
makes sure that while this QTS-generated file can stay in the tree,
these obscure macros do not ooze into the namespace anymore.

Introduce accessor iocsr_get_config_table() for retrieving IOCSR config
tables. This patch is again trimming down the namespace polution.
The IOCSR config tables are used only by scan manager, they are generated
by qts and are board specific. Before this patch, the approach to use
these tables in scan manager was to define an extern variable to silence
the compiler and compile board-specific iocsr_config.c into U-Boot which
defined those extern variables. Furthermore, since these are tables and
the scan manager needs to know the size of those tables, iocsr_config.h
is included build-wide.
This patch wraps all this into a single accessor which takes the scan
chain ID and returns pointer to the table and it's size. All this is
wrapped in wrap_iocsr_config.c board-specific file. The file includes
the iocsr_config.c (!) to access the original tables and transitively
iocsr_config.h . It is thus no longer necessary to include iocsr_config.h
build-wide and the namespace polution is trimmed some more.

Extract the clock configuration horribleness caused by pll_config.h in
the following manner.
First of all, introduce a few new accessors which return values of
various clocks used in clock_manager.c and use them in clock_manager.c .
These accessors replace those few macros which came from pll_config.h
originally. Also introduce an accessor which returns the struct cm_config
default configuration for the clock manager used in SPL.
The accessors are implemented in a board-specific wrap_pll_config.c
file, whose sole purpose is to include the qts-generated pll_config.h
and provide only the necessary values to the clock manager.
The purpose of this design is to limit the scope of inclusion for the
pll_config.h , which thus far was included build-wide and poluted the
namespace. With this change, the inclusion is limited to just the new
wrap_pll_config.c file, which in turn provides three simple functions
for the clock_manager.c to use.

Add a stub s_init function in the board file. The reason why the stub function
is needed is that most of the work is now being done in board_init_f(), there
is no need for the SPL to do anything s_init(). However, since lowlevel_init()
is still branching to s_init(), we need stub function for now, until
lowlevel_init() morphs into s_init().
