Daniel Thompson f9733e492d misc: Let the compiler choose whether to omit frame pointer
Currently CONFIG_OMIT_FRAME_POINTER is a boolean and defaults to N,
which increases code size. This is intended to improve debugability
but on many architectures the use of this option does not actually
compromise debugging. Further the compiler already knows whether or not
omitting the frame pointer is harmful to debugging and its defaults
are selected accordingly.

By making this choice optional we can have a sane default on *all*
architectures by letting the compiler decide for us.

This patch significantly improves the default code generation on
arm (thumb), nios2 and arc. The benefit looks to be about between 5%
and 10% code size reduction depending upon architecture). x86 is
unaffected.

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.

Anas Nashif fe958df4dd libc: rework libc selection and reduce Kconfigs
Moved all libc Kconfigs to where the code is and remove the default
Kconfig for selecting the minimal libc. Minimal libc is now the default
if nothing else is configured in.

Removed the options for extended libc, this obviously was restricting
features in the minimal libc without a good reason, most of the
functions are available directly when using newlib, so there is no
reason why we need to restrict those in minimal libc.

Andrew Boie 82f11bf099 build: x86: add some flexibility in custom linker scripts
If a particular project needs to add additional data to the
binary image, in most cases the entire linker script needs to
forked into the project space, causing maintenance issues if
the main linker script is changed.

Now we add some Kconfig options to allow a project to specify
some additional linker scripts which get included by the main
one in a few key areas:

1) In the definition to the 'rodata' section, which can allow
additional data to be included in this ROM section.

2) In the definition to the 'datas' section, which allows
additional data to be included in this RAM section.

3) Arbitrary additional sections to be included at the end of
the binary.

For 1 and 2, this is useful to include data generated outside of
the normal C compilation, such as data structures that are created
by special build tools.

3 is useful for including arbitrary binary blobs inside the final
image, such as for peripheral or co-processor firmware.

Juro Bystricky f3bf5abd52 newlib: add support for nano-formatted-io
If newlib is configured with --enable-newlib-nano-formatted-io,
floating-point support is split out of the formatted I/O code into
weak functions which are not linked by default. This leads to a smaller
code by about 16~20k when using newlib "printf" and/or "sscanf" but not
using floating point I/O.

Programs that need floating-point I/O support must explicitly request
linking of one or both of the floating-point functions:

    _printf_float or _scanf_float.

This can be done at link time using the -u option which can be passed
to either gcc or ld.

Implemented via new configuration options:
    CONFIG_NEWLIB_LIBC_FLOAT_PRINTF
    CONFIG_NEWLIB_LIBC_FLOAT_SCANF

Anas Nashif ecf96d2cfa arduino 101: make factory bootloader config the default
The Arduino 101 comes with a bootloader that supports DFU
and flashing of all cores using the dfu-util package.

This changes the memory layout of the image built for the
Arduino 101 and remove previous work-arounds to allow booting,
including the version-header section in the linker script.

The bootloader expects the text section at +0x30 from the physical
load address and thus requires special treatment in the linker
script.

Other changes by Andrew Boie:
The flash size parameters were both wrong. X86 side has 192K
of flash from 0x4003000 - 0x40060000, the entire span of
sys_flash1.

ARC side is now the span from 0x40010000 - 0x40030000, 128K.

   _mem_safe_read()
   _mem_safe_write()
   _mem_safe_write_to_text_section()
Those routines will return an error if the memory is not accessible rather
than potentially crash.

This implementation is based on the image's boundaries; thus it allows
read/write access to the data/bss/init sections and read access only to
the text/rodata sections.  All other memory is considered invalid, even
if addressable. This includes the leftover from the RAM at the end of
the image, since there is no support for using it (e.g. there is no
dynamic allocator).
