license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

menuconfig FLASH
Kconfig: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.

drivers: flash: add a generic spi nor flash driver This driver is inspired from the w25qxxdv SPI NOR flash driver which was already implementing the CFI (Common Flash Interface) for its purpose. To handle other NOR flash a flash id table (as Linux do) which contains the geometry for a few SPI NOR flash based on their JEDEC ID has been introduced. We currently support the following flash: - W25Q80 - W25Q16 - W25Q32 - S25FL216K - MX25UM512 The read and write functions are able to handle more then one page at a time and return the number of bytes read or write. Also because every NOR flash expect to disable the write protection before writing or erasing, the write enable command is now part of the write and erase functions.
