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.

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.

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 Change-Id: I05be0d5ed4c1a49b23dca1550ee66fd5891044d2 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

Include the reset vector stub, which enables instruction/data caches
and then jumps to __start. This code is typically located at the very
beginning of flash memory. You may need to omit this if using the
nios2-download tool since it refuses to load data anywhere other than
RAM.

Have exceptions print additional useful debugging information in
human-readable form, at the expense of code size. For example,
the cause code for an exception will be supplemented by a string
describing what that cause code means.

nios2: support more global pointer scenarios 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.

Use global pointer relative offsets for small globals declared
anywhere in the executable. Note that if any small globals that are put
in alternate sections (such as _k_task_list_ptr) they must be declared
in headers with proper __attribute__((section)) or the linker will
error out.

Use GP relative access for all data in the program, not just
small data. Use this if your board has 64K or less of RAM.
