Implemented using the unwound bytewise implementation from
https://en.wikipedia.org/wiki/Computation_of_cyclic_redundancy_checks

Since 2.14.1 release mbedTLS has a few API changes and deprecation which
do not affect the Zephyr code and a new MBEDTLS_CHECK_PARAMS option that
enables validation of parameters in the API. A list with all changes can
be found in:
./ext/lib/crypto/mbedtls/ChangeLog
Note that this version will become the basis of the next LTS (Long Term
Support) branch that will be maintained for the next 3 years until at
least the end of 2021.

This seems to solve the issue with GH-12033. There seems to be
some compiler optimization that was causing this issue. This
occurs only when the build is re-run by invoking cmake without
clearing the previous build.

Change arg_len to be u16_t in shell_history_get since it is returning
a value that can be hold by u16_t.
Signed-off-by: Flavio Ceolin <flavio.ceolin@intel.com>
Everywhere the return of this function was being assigned to u16_t to
save space on stack. Instead of casting in all these places (and may
end up with overflow), just changing this function's return.
Note that the function itself is not checking for overflow yet since
I'm not sure this can happen and/or is a problem. Though now we have
only one single point to fix this problem.

Since 2.12.0 release mbedTLS has an important security fix concerning
RSA PKCS#1 v1.5 decryption (CVE-2018-19608). Besides that it has very
few API changes, and the usual set of functional improvements, security
fixes and bug fixes. A list with all changes can be found in:
./ext/lib/crypto/mbedtls/ChangeLog

In general driver system calls are implemented at a subsystem
layer. However, some drivers may have capabilities specific to
the hardware not covered by the subsystem API. Such drivers may
want to define their own system calls.
This macro makes it simple to validate in the driver-specific
system call handlers that not only does the untrusted device
pointer correspond to the expected subsystem, initialization
state, and caller permissions, but also that the device object
is an instance of a specific driver (and not just any driver in
that subsystem).

Return actual pixel format that is in use by the SDL display driver

Signed-off-by: Jan Van Winkel <jan.van_winkel@dxplore.eu>
If any of the Zephyr version numbers went beyond 99, the "%2d" printf
specifiers would expand to fit and the string would run over the
memory on the stack used for os_str[].
Recent GCC versions (remember native_posix and x86_64 use the host
compiler) were actually detecting this and correctly issuing a warning
(but only if the 3-digit char value would overflow the actual array
size!), which was breaking sanitycheck for me on Fedora 28 and Ubuntu
18.04 build hosts. Pretty impresive warning.
As it happens this was wasteful anyway; we were spending bytes on the
stack (and in rodata to store the constant which, and the cycles
needed to copy it into place on the stack where it would be
overwritten immediately) when we could just snprintf() directly into
the buffer the user gave us.

NVS with modified flash layout. At the end of a sector a special ate is
placed that points to the last ate that was written. This special ate
is written when a sector is closed. This allows nvs to travel through
the fs much quicker as it doesn't have to search for the last ate in
a sector.
This modification also speeds up the nvs_init procedure that was very
slow on external (spi) flash.
Remark: As the layout of data in flash is changed old data in the flash
cannot be recovered. It is advised to erase the nvs flash area before
using the changed nvs.
Modification after review by @nvlsianpu applied
Modification after review by @aurel32:
_nvs_prev_ate(): provide a backup search of a valid ate when the sector
close_ate has a bad CRC8. Tested on nrf81522 by making flash writing
bad data to the sector closing ate. Also validated that if a valid ate
is overwritten the filesystem keeps working.
_nvs_gc(): return error if _nvs_flash_cmp_const() is < 0.

If the test process returns an error (return code != 0),
it should be considered a failure, even if the handler
considers the test passed.
But this is not done when we are killing (SIGTERM) the processes,
as then the return code is not necessarily sensible.
Without this, for example, when running with valgrind, all valgrind
errors are missed.

Added a valgrind error supression file which can be used when
running in the POSIX arch.
So far we are supressing 2 types of errors:
* One very normal in glibc, which will be triggered in the nrf52_bsim
* 2 due to the posix arch prioritizing terminating fast over terminating
cleanly. The posix arch, when posix_core_clean_up() is called, will
pthread_cancel all Zephyr threads. But it will NOT wait for them to
finnish, in case any of them was hung or there is any other problem
which would prevent it. Therefore, depending on the execution, some
times the threads will be still lingering when the main thread exits
Somethign similar applies to posix_soc_clean_up().
These 2 are not errors, but conscious choices => Therefore we
supress them

LTO is not supported yet, but there are a handful of references to the
flag '-flto' and the non-existent Kconfig option 'LTO'. To not confuse
users about whether LTO is supported or not, we should remove this
dead code.
As an aside, prototyping has shown that supporting LTO will give
signicant (10%) code size improvments, but will not be trivial to
support due to how we process object files with python.

Enable by default the following hardware instances in Kconfig:
- ADC_0
- I2C_0
- SPI_1 (SPI_0 for nRF52810)
for all nRF development kit boards having the corresponding DT nodes
enabled. This way there is no need to enable these instances in
particular applications, like samples for sensors or tests for drivers.
I2C_0 and SPI_0 cannot be used simultaneously in most of nRF SoCs,
nRF52810 is the only exception so far (and in this SoC SPI_1 is not
present, hence SPI_0 is enabled for it).

- I2C

Kconfig options enabling these drivers depend on both a given hardware
feature (e.g. I2C) and an nRF family SoC selected, so effectively they
will be automatically enabled only when it is adequate (and in most
cases these drivers are the only option for a given hardware feature
on nRF SoCs).
