8eaff5d6d2 k_thread_abort(): assert if abort essential thread
Previously, this was only done if an essential thread self-exited,
and was a runtime check that generated a kernel panic.

Now if any thread has k_thread_abort() called on it, and that thread
is essential to the system operation, this check is made. It is now
an assertion.

_NANO_ERR_INVALID_TASK_EXIT checks and printouts removed since this
is now an assertion.

In benchmark test (test_info) while making function call regs
r0 - r4 are modified into called function. Due to this value
inside r3 is getting lost.
This patch saves and restore the value in r0-r4 regs while making

76b577e180 tests: benchmark: timing_info: Change API/variable Name.
The API/Variable names in timing_info looks very speicific to
platform (like systick etc), whereas these variabled are used
across platforms (nrf/arm/quark).
So this patch :-
1. changing API/Variable names to generic one.
2. Creating some of Macros whose implimentation is platform

ecb0f3e159 arm: mpu: Account for stack guard size correctly
This patch fixes a couple of issues with the stack guard size and
properly constructs the STACK_ALIGN and STACK_ALIGN_SIZE definitions.

The ARM AAPCS requires that the stack pointers be 8 byte aligned.  The
STACK_ALIGN_SIZE definition is meant to contain the stack pointer
alignment requirements.  This is the required alignment at public API
boundaries (ie stack frames).

The STACK_ALIGN definition is the required alignment for the start
address for stack buffer storage.  STACK_ALIGN is used to validate
the allocation sizes for stack buffers.

The MPU_GUARD_ALIGN_AND_SIZE definition is the minimum alignment and
size for the MPU.  The minimum size and alignment just so happen to be
32 bytes for vanilla ARM MPU implementations.

When defining stack buffers, the stack guard alignment requirements
must be taken into consideration when allocating the stack memory.
The __align() must be filled in with either STACK_ALIGN_SIZE or the
align/size of the MPU stack guard.  The align/size for the guard region
will be 0 when CONFIG_MPU_STACK_GUARD is not set, and 32 bytes when it
is.

The _ARCH_THREAD_STACK_XXXXXX APIs need to know the minimum alignment
requirements for the stack buffer memory and the stack guard size to
correctly allocate and reference the stack memory.  This is reflected
in the macros with the use of the STACK_ALIGN definition and the
MPU_GUARD_ALIGN_AND_SIZE definition.

85481d997b arch: arm: Remove redundant check and fix rounding
This patch removes the redundant stack alignment check being done.  The
stack definition macros enforce the alignment requirements via the
__align() directives.

In addition, fix the rounding down of the psp to be correct.  The
actual initial stack pointer is the end of the stack minus the size of
the __esf structure.  Rounding down after the subtraction will get us
to the correct offset.

4f67a6c76d cc3200: Remove TI cc3200 SOC and LaunchXL board support
Per ZEP-1958, Phase 2 of adding CC3220sf LaunchXL support,
was to "deprecate the CC3200 launchxl support in Zephyr
(redundant to the CC3220)."

Effectively, the CC3220 SOC replaces the CC3200.

This patch removes the following:
* the imported CC3200 SDK
* CC3200 SOC, board, DTS files.
* adjusts other files where cc3200 was mentioned.

Also, it fixes explicit references to CC3200 in generic
CC32xx driver files.

1a5537811f cc32xx: Redefine CMSIS IRQn_Type enum to unsigned int
Previously, calling NVIC_SetPriority(IRQn_Type irqn, ....) with
the NWP interrupt number of 171 caused a hard fault during a
subsequent svc #0 instruction during _Swap().

GNU compiler is generating a bit extension instruction (sxtb) which
converts a positive IRQ value argument to a negative value when
casting to the CMSIS IRQn_Type enum parameter type.

This generates a negative index, which then writes to an SCB
control register instead of NVIC register, causing a hard
fault later on.

This issue only occurs when passing interrupt numbers > 0x80
(eg: 171 (0xab) for the NWP) to the CMSIS NVIC apis.

The solution here is simply to redefine IRQn_Type to be an
unsigned 32 bit integer, while redefining the CMSIS IRQn_Type
enum definitions for interrupts less than zero.

eb48a0a73c arm: armv6-m: Support relocating vector table
An abnormal crash was encountered in ARMv6-M SoCs that don't have flash
starting at 0.  With Zephyr OS the reason for this crash is that, on
ARMv6-M the system requires an exception vector table at the 0 address.

We implement the relocate_vector_table function to move the vector table
code to address 0 on systems which don't have the start of code already
at 0.

 to copy vector table]

507852a4ad kernel: introduce opaque data type for stacks
Historically, stacks were just character buffers and could be treated
as such if the user wanted to look inside the stack data, and also
declared as an array of the desired stack size.

This is no longer the case. Certain architectures will create a memory
region much larger to account for MPU/MMU guard pages. Unfortunately,
the kernel interfaces treat both the declared stack, and the valid
stack buffer within it as the same char * data type, even though these
absolutely cannot be used interchangeably.

We introduce an opaque k_thread_stack_t which gets instantiated by
K_THREAD_STACK_DECLARE(), this is no longer treated by the compiler
as a character pointer, even though it really is.

To access the real stack buffer within, the result of
K_THREAD_STACK_BUFFER() can be used, which will return a char * type.

This should catch a bunch of programming mistakes at build time:

- Declaring a character array outside of K_THREAD_STACK_DECLARE() and
  passing it to K_THREAD_CREATE
- Directly examining the stack created by K_THREAD_STACK_DECLARE()
  which is not actually the memory desired and may trigger a CPU
  exception
