Anas Nashif 3ae52624ff 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.

Michael Hope 42accf2e64 disk: add a SDHC card over SPI driver.
Features:

- Uses the SPI bus to communicate with the card
- Detects and safely rejects SDSC (<= 2 GiB) cards
- Uses the optional CRC support for data integrity
- Retries resumable errors like CRC failure or temporary IO failure
- Works well with ELMFAT
- When used on a device with a FIFO or DMA, achieves >= 310 KiB/s on a
  4 MHz bus

Tested on a mix of SanDisk, Samsung, 4V, and ADATA cards from 4 GiB to
32 GiB.

Ramakrishna Pallala 2b5b7da9f3 subsys: disk: Add support for multiple disk interfaces
Add support for enabling multiple disk interfaces (Flash, RAM)
simultaneously in Zephyr by introducing a simple disk interface
framework where we can register multiple disks which would
interface with different storage devices. This would enable us
to have multiple instances of FATFS in Zephyr.

Add support for mass storage drive disk name which will be
used as an argument when calling the disk interface API's.

Enable multiple volumes support configuration in
ELM FAT library.

Sebastian Bøe 12f8f76165 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
