Version 0.2.8 of this library has been released on Aug 29, and this
patch updates the library from version 0.2.7. A summary of changes
is available at the official repository at:
https://github.com/01org/tinycrypt/releases/tag/v0.2.8
A number of the changes we already had in tree, so the import to sync
with v0.2.8 is pretty minor.

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 should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware. Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.

Zeroing out 2*NUM_ECC_WORDS bytes starting from the `p2` pointer would
not only write 16 bytes to an 8-byte array allocated on the stack, but
also not clear out important arrays such as `_private` and `tmp`.
Moreover, no memory was cleared out before returning from the function,
and there are two exit points.
Properly memset() all private data and use an empty assembly block
referencing the memory region to avoid the memset() calls to be elided
by the compiler.
Ideally, in the future, all stack-allocated variables that contains
sensitive information should be marked with __attribute__((cleanup)), a
GCC extension that calls a function when the variable exits the scope.
This will not only reduce code size, but for other functions with
multiple exit points, also ensure that sensitive data is always
cleared.

Version 0.2.7 of this library has been released on June 30th, and this
patch updates the library from version 0.2.6. A summary of changes
is available at the official repository at:
https://github.com/01org/tinycrypt/releases/tag/v0.2.7
There were some API changes in this version, so some tests are not
building: ccm_mode, ecc_dh, and ecc_dsa. Fixes to these tests and
subsystems affected by the changes will be provided.

Update Zephyr's tinycrypt to version 2.0. This new version adds support
for ECC_DH, ECC_DSA, CMAC, & CTR_PRNG.
The following doxygen documentation typos were detected and fixed:
- ctr_prng.h:84 change plen by pLen,
- ctr_prng.h:109 change entropylen by entropyLen,
- sha256.h:110 change Sha256 by s.
ecc_dh.h is also modified to fix the discrepancy of ecc_make_key
definition and declaration.
See https://gerrit.zephyrproject.org/r/#/c/1982/
TC_FAIL and TC_SUCCESS defines are renamed in this new version of
tinycrypt, so net/bluetooth/hci_core.c, net/bluetooth/hci_ecc.c and
net/bluetooth/smp.c are also updated to reflect those changes.

Tinycrypt is maintained at github and thus should be treated as an
external library and hosted under ext/.
