David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
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.

Jira: ZEP-1457

Andrew Boie 543aa77392 nios2-qemu: fix CONFIG_XIP
It's all RAM, but we pretend the range 0x410000 - 0x420000
is the "ROM" region, and stuff gets copied into RAM starting
at 0x400000.

Andrew Boie a7b54980bd nios2: set appropriate compiler flags for math support
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

Kumar Gala b757c1ccba nios2: remove empty files from nios2e-zephyr
Use a kbuild trick to force built-in.o to get built even if there isn't
any code so we can link properly.  This is cleaner than keeping around
empty files that don't do anything.

Andrew Boie 3b9302158c nios2: set up common linker script for XIP and non-XIP
We will require 6 variables to be defined by SOC-specific
linker script; these values in turn can be pulled from
defines in layout.h.

To help position code correctly we define two new ELF sections
for this arch, 'reset' and 'exceptions'.

Andrew Boie 8564875a98 nios2: provide and include soc-specific headers
BSP builds for Nios II generate a linker.h and system.h which reflects
the configuration for that CPU. This can vary depending on how the CPU
is wired up in QSYS, so it needs to be at the SOC level--we essentially
treat any given CPU configuration as a SOC in Zephyr build terms.

Include these files from <arch/cpu.h>.

Andrew Boie 9433895954 nios2: basic build, non-functional
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.
