license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

subsys: fs: Add Flash Circular Buffer Zephyr already supports NFFS as a storage layer, but it might be a little bit too heavyweight for certain applications in memory-restricted ICs. This module is response for need of Lightweight flash storage capability. FCB is ported form MyNewt as native zephyr module. Signed-off-by: Andrzej Puzdrowski <andrzej.puzdrowski@nordicsemi.no>

cmake: default to linking 'app' with the interface library 'FS' This patch removes the need for application build script code to explicitly link 'app' with a filesystem implementation. It does this by introducing a zephyr interface library called 'FS' that contains the usage requirements for linking with the filesystem library subsys__fs and using Kconfig to default to linking the 'app' library with this interface library.

zephyr_interface_library_named(FS)
Introduce cmake-based rewrite of KBuild 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 PR: zephyrproject-rtos#4692 docs: http://docs.zephyrproject.org/getting_started/getting_started.html Signed-off-by: Sebastian Boe <sebastian.boe@nordicsemi.no>

zephyr_library()
subsys/fs: add implementation helper module File system API functions that operate on paths are passed both the absolute path including the mount point prefix, and the mount point within which the path lies. Unfortunately it's not entirely trivial to convert an arbitrary path within the file system space to an absolute path within its mount point, because the path may be to the mount point itself and not end with a directory separator. The effect is that a file system implementation like nffs may be given an empty path when "/" is required. Add an implementation module that does this transformation and use it to transform paths within each filesystem wrapper. Signed-off-by: Peter A. Bigot <pab@pabigot.com>

subsys: fs: Add Non Volatile Storage (NVS) for zephyr Zephyr supports fatfs, nffs and fcb as storage layer. fatfs and nffs are less suited for application in memory restricted IC's. fcb has a smaller footprint but has a complex api. The proposed module is a module with a even smaller footprint compared to fcb and a simple interface for reading and writing entries. The module provides wear levelling of flash. This allows the module to be used not only to store configuration settings but to store device state (e.g. state of a light switch over reboots) of a zephyr device. Fixes buffer overflow by introducing maximum read length in nvs_read() and nvs_read_hist(). Fixes nvs_write() not to reflash the same data. Allows the user to do call nvs_write() for all defined entries without worries about flash wear. Fixes garbage collection error where wrong data could be copied. Add nvs_delete() to allow deleting a stored entry. A deleted entry will not be copied to a new flash sector Include flash wear information in the README.md documentation 0/25 Update module after reviewers remarks, added documentation to nvs.h, removed README.md by nvs.rst in doc/subsystems folder 04/26 Update module after reviewers remarks, updated nvs.rst, added more documentation to samples/subsys/nvs/src/main.c, updated doxygen info in nvs.h (hope this time it works). 04/26 Update subsystems.rst to include nvs.restart 04/27 Updated nvs.c and nvs.h to avoid a possible flash deletion loop when the file system is full. 04/29 Updated nvs_write to detect and ignore deletes of non-existing items 05/06 Update NVS module to return standard error codes, removed low level API, added configuration options. NVS now uses the board dts to determine the flash storage location (FLASH_AREA_STORAGE_OFFSET). 05/06 Update nvs.rst. Updated intendation and added intermediate variables in nvs.c to make the code easier to read. 05/06 Update nvs.rst. 05/07 Update nvs.rst 05/08 Changed the API to a more standard file system API. 05/08 Removed cnt_max from nvs_read() as it is not used. 05/08 Removed #ifdef(CONFIG_NVS_LOG) from nvs_priv.h, now the module can be build with debugging off. 05/09 Removed configuration options for SECTOR_SIZE, SECTOR_COUNT and MAX_ELEM_SIZE. It is now easy to support multiple NVS filesystems on one or multiple devices. Changed logging to support newlib systems. Thanks to Olivier Martin for reporting and proposed changes.
