This patch adds Big Endian architecture support. Even if a compiler
generating big endian object files is used, our linker script, or
include/linker/linker-tool-gcc.h to be precise, has default output
format as little endian.
This patch adds a hidden config CONFIG_BIG_ENDIAN, which should be set
by big endian architectures or a SoC's, and adds an condition to
switch OUTPUT_FORMAT in our linker.cmd.

Some terminals literally interprets shell output data. Hence to print
a message in new line shell needs to send `\r\n` each time. To minimize
flash usage user can now send `\n` as a line delimiter and shell will
automatically add missing CR character.

In ARMv8-M MPU it is not possible to have the following access

K_MEM_PARTITION_IS_WRITABLE macro separately for v8M and v7M MPU
architectures (in the separate include files).

The Cypress PSoC6 specifies some input sections in the startup
scripts. These sections (.heap, .stack, etc.) need to be placed
at correct location.
Signed-off-by: Daniel Leung <daniel.leung@intel.com>
This allows the SoC to specify some additional linker script
fragments into the bss, data and read-only data sections.
For example, the Cypress PSOC6 has a few input sections that
must be put into bss and data sections. Without specifying
these in the linker script, they are consider orphan sections
and the placement is based on linker heuristic which is
arbitrary.
POSIX is not supported as the main linker script is
provided by the host system's binutils and we have no control
over it. Also, currently Xtensa SoCs have their own linker
scripts so there is no need to this feature.

From-current-dir includes like "sys/types.h" are dangerous - they
turn out to cause #include_next directive to not work as expected -
instead of including next file (which is in our case should be
libc's), it will include the same file once again (apparently
because with #include "", a file is found from the current dir,
so next search will countinue with -Iinclude/posix, and find
sys/types.h there again).

k_queue has k_queue_append API which does not check if the element's
address already exists. This creates a problem if the same element
address is appended to queue. This forms circular list showing
unintended behaviour for the application using queue. The proposed
API k_queue_find_and_append takes care of checking if element exists
already before appending. This API is complimentary to k_queue_remove
which checks if the queue element is present before removing.

are zeroed to make the correction field be set to 0. This mimics the
behavior of openAvnu (a Linux gPTP client). For full compliance the

Macro _OBJECT_TRACING_NEXT_PTR expands to a member or to nothing.
Macro _OBJECT_TRACING_NEXT_PTR is used in a number of places, like:
struct k_stack {
.. omitted ..
_OBJECT_TRACING_NEXT_PTR(k_stack);
u8_t flags;
};
When the macro expands to nothing, a lonesome semi would remain. This is
illegal in C99, but permitted in GCC with GNU extensions.
Rather than expand to empty, we now expand to a zero-length array.
This means we can retain the trailing semis across structs wherein the
macro is used.
Note that zero-length array (foo[0]) != flexible array member (foo[]):
* zero-length array: Is GNU+Clang extension. Anywhere in struct.
* flexible array member: Is C99. Only in end of struct.
Thus we have really only traded-off one portability issue for
another, more acceptable, one at least.
