Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Until now, Zephyr has used a patched Kconfiglib that turns 'source' into
a globbing source (by replacing 'source' with 'gsource' at the token
level). There's two problems with this:
- The patch needs to be maintained separately
- Misspelled filenames are silently ignored, as they look like glob
patterns that don't match anything
Fix it as follows:
1. Replace all 'source' statements that use wildcards with 'gsource'
2. Remove the custom Kconfiglib patch so that 'source' no longer globs
The sed pattern '/source.*[*?]/s/source/gsource/' was run over all
Kconfig* files to do the replacement.
source's that use environment variables that might contain glob patterns
were manually changed to gsource.
Building the docs in doc/ is a good test, as doc/Makefile deliberately
sets the environment variables to glob up as many Kconfig files as
possible.

Not all boards require the various binary formats zephyr generates. So
be selective based on the arch, SoC or board and only geenrate the
binaries actually needed.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Completing the terminology change started with change 4008
by updating the Kconfig files processed to produce the
online documentation, plus header files processed by
doxygen. References to 'platform' are change to 'board'

Arches now select whether they want to use the GCC built-ins,
their own assembly implementation, or the generic C code.
At the moment, the SDK compilers only support builtins for ARM
and X86. ZEP-557 opened to investigate further.

This is at the expense of code size. The QEMU and MAX10
targets have plenty of space so enable it for these boards,
but leave off by default for others.

We now allow use of -mgpopt=global and -mgpopt=data. The 'global'
option is now the default instead of compiler-default local, expanding
global pointer usage to all small data in the system.
For systems where all RAM is less than 64K, the 'data' option may be
appropriate.
Some fixes had to be made to the system in order to get around some
issues:
* prep_c.c no longer uses fake linker variables to figure out the size
of data or BSS, as these gave the linker fits as it tried to compute
relative addresses to them.
* _k_task_ptr_idle is create by sysgen and placed in a special section.
Any small data in a special section needs to be declared extern
with __attribute__((section)) else the compiler will assume it's in
.sdata.
* same situation with extern references to k_pipe_t (fixed pipe_priv
test)
For legacy applications being ported to Nios II which do things that
freak out global pointer calculation, it can be disabled entirely.

Nios II CPUs vary in configuration on whether they support
'mul', 'mulx', and 'div' family of instructions. The compiler
can be told to use GCC integer library routines instead if
needed.
Ideally we would just pull the configuration out of system.h,
but pulling include file #defines into the Make environment
will involve some build system work that is best left to a
later improvement.
We've decided to take this build-time approach rather than
handle unimplemented instruction exceptions, so remove the
hook in exception.S

If XIP is turned on, only hardware breakpoints may be used, and
code cannot be loaded onto the device with nios2-download

enable this if they need to.

Basic build framework for Nios2. Everything is stubbed out,
we just want to have a build going so that we can start to
parallelize implementation tasks.
This patch is not intended to be functional, but should be
able to produce a binary for all the nanokernel-based
sanity checks.
