Adds the mimxrt1052 SoC, which belongs to a new family (nxp_imx) and
series (rt) of SoCs. The mimxrt1052 integrates an Arm Cortex-M7 core,
512 KB TCM, and many peripherals including 2D graphics, an LCD display
controller, camera interface, SPDIF and I2S. Unlike other SoCs in
Zephyr, the mimxrt1052 has no internal flash.
This initial port to mimxrt1052 configures the system clock to operate
at 528 MHz, and enables the serial/uart and gpio interfaces to support
the hello_world and blinky samples. Support for additional Zephyr driver

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

This adds CONFIG_EXECUTE_XOR_WRITE, which is enabled by default on
systems that support controlling whether a page can contain executable
code. This is also known as W^X[1].
Trying to add a memory domain with a page that is both executable and
writable, either for supervisor mode threads, or for user mode threads,
will result in a kernel panic.
There are few cases where a writable page should also be executable
(JIT compilers, which are most likely out of scope for Zephyr), so an
option is provided to disable the check.
Since the memory domain APIs are executed in supervisor mode, a
determined person could bypass these checks with ease. This is seen
more as a way to avoid people shooting themselves in the foot.

Currently this is defined as a k_thread_stack_t pointer.
However this isn't correct, stacks are defined as arrays. Extern

treats it as a pointer to the stack array and not the array itself.
Declaring as an unsized array of k_thread_stack_t doesn't work
well either. The least amount of confusion is to leave out the
pointer/array status completely, use pointers for function prototypes,
and define K_THREAD_STACK_EXTERN() to properly create an extern

Add the following application-facing memory domain APIs:

k_mem_domain_destroy() - to destroy a memory domain
k_mem_domain_add_partition() - to add a partition into a domain
k_mem_domain_remove_partition() - to remove a partition from a domain
k_mem_domain_add_thread() - to add a thread into a domain
k_mem_domain_remove_thread() - to remove a thread from a domain
A memory domain would contain some number of memory partitions.
A memory partition is a memory region (might be RAM, peripheral
registers, flash...) with specific attributes (access permission,
e.g. privileged read/write, unprivileged read-only, execute never...).
Memory partitions would be defined by set of MPU regions or MMU tables
underneath.
A thread could only belong to a single memory domain any point in time
but a memory domain could contain multiple threads.
Threads in the same memory domain would have the same access permission
to the memory partitions belong to the memory domain.
The memory domain APIs are used by unprivileged threads to share data
to the threads in the same memory and protect sensitive data from
threads outside their domain. It is not only for improving the security
but also useful for debugging (unexpected access would cause exception).

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.

This patch removes the redundant stack alignment check being done. The

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.

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

Clearing fields in the region descriptor attributes doesn't always have
the expected effect of revoking permissions. In the case of bus master
supervisor mode fields (MxSM), setting to zero actually enables read,
write, and execute access.
When we reworked handling of region descriptor 0, we inadvertently
enabled execution from RAM by clearing the MxSM fields and enabling the
descriptor. This caused samples/mpu_test run to throw a usage fault
instead of an MPU-triggered bus fault.
Fix this by setting all the MxSM fields to 2'b11, which gives supervisor
mode the same access as user mode.

Both the ARM and NXP MPU drivers incorrectly calculated the region index
by assuming the region type (e.g., THREAD_STACK_GUARD_REGION) was
zero-indexed, when in reality it is one-indexed. This had the effect of
wasting one region.

The NXP MPU requires special handling of region descriptor 0 to
guarantee that the debugger has access to the entire address space. It
does not allow writes from the core to affect the start or end
addresses, or the permissions associated with the debugger.
The original implementation of this driver attempted to work around
region descriptor 0, resulting in an off-by-1 error caught by Coverity.
Instead, define region descriptor 0 explicitly in the mpu_regions array,
and add some asserts to ensure that one doesn't try to change its start
or end addresses. This has an added benefit such that more permissions
can be enabled in region 0 if desired, whereas the previous
implementation always forced all writable permissions to be cleared.

The original implementation of _get_num_regions() parsed the CESR[NRGD]
register field to determine the number of mpu region descriptors
implemented in hardware. There was a possible path in the code to return
zero, which would cause underflow later on in arm_core_mpu_configure().
Coverity complained despite an assert to catch this condition. Instead,
use a preprocessor macro from mcux that defines the number of mpu region
descriptors.

Stack sentinel doesn't prevent corruption, it just notices when
it happens. Any memory could be in a bad state and it's more
appropriate to take the entire system down rather than just kill
the thread.
Fatal testcase will still work since it installs its own
_SysFatalErrorHandler.

One of the stack sentinel policies was to check the sentinel
any time a cooperative context switch is done (i.e, _Swap is
called).
This was done by adding a hook to _check_stack_sentinel in
every arch's __swap function.
This way is cleaner as we just have the hook in one inline
function rather than implemented in several different assembly
dialects.
The check upon interrupt is now made unconditionally rather
than checking if we are calling __swap, since the check now
is only called on cooperative _Swap(). The interrupt is always
serviced first.

The REGION bits (bit[3:0]) of MPU_RBAR register can specify the number
of the region to update if the VALID bit (bit[4]) is also set.
If the bit[3:0] of "region_addr" are not zero, might cause to update
unexpected region. This could happen since we might not declare stack
memory with specific alignment.
This patch will mask the bit[4:0] of "region_addr" to prevent updating
unexpected region.

The kernel tracks time slice usage with the _time_slice_elapsed global.
Every time the timer interrupt goes off and the timer driver calls
_nano_sys_clock_tick_announce() with the elapsed time, this is added to
_time_slice_elapsed. If it exceeds the total time slice, the thread is
moved to the back of the queue for that priority level and
_time_slice_elapsed is reset to zero.
In a non-tickless kernel, this is the only time _time_slice_elapsed is
reset. If a thread uses up a partial time slice, and then cooperatively
switches to another thread, the next thread will inherit the remaining
time slice, causing it not to be able to run as long as it ought to.
There does exist code to properly reset the elapsed count, but it was
only compiled in a tickless kernel. Now it is built any time
CONFIG_TIMESLICING is enabled.

The STM32F413ZH has 1536kB of Flash and 320kB of SRAM. This
configuration is currently not supported by ST MPU driver, so fill in
the blanks.
Note: The MPU does not support region size that is not a power-of-2 (see
the SIZE field in the MPU_RASR register). This is a problem for our
1536kB Flash region, so it was rounded up to the nearest choice. This is
possible because the memory in the range 0x0818000 - 0x0FFFFFFF is
"Reserved" and thus not mapped anyway.

The STM32L4x SoCs embeds a slightly different embedded flash controller
from the STM32F4x SoCs.
This particular controller has the following properties :
- Up to 2 512KiB banks divided in 2KiB pages
- Flash can be accessed in any sizes
- Flash must be written in 64bit aligned 64bit double-words
The drivers/flash/flash_stm32f4x.c is refactored into a new common
drivers/flash/flash_stm32.c and drivers/flash/flash_stm32l4x.c is
created with the STM32L4x specific functions.
To ease the refactoring and keep common functions, the STM32L4x flash
headers are slightly modified to match the hardware reference naming
and solve compilation issues.
