With upcoming ICs that are not in the nRF5x family, rename the flash
driver and all its dependencies from nrf5 to nrf.
Should also fix the issue introduced by f49150cab6 which broke the
assignment of the flash device due to a partial rename.

Upcoming Nordic ICs that share many of the peripherals and architecture
with the currently supported nRF5x ones are no longer part of the nRF5
family. In order to accomodate that, rename the SoC family from nrf5 to
nrf, so that it can contain all of the members of the wider Nordic
family.

Keyword FLASH_HAS_PAGE_LAYOUT is related to flash and should
be declared in its Kconfig.

It was possible to have enable flash module while no flash driver
implementation was enabled. This cause coverity issues and unnecessary
initialization call.
This pat introduce FLASH_HAS_DRIVER_ENABLED Kconfig keyword which is
selected once any flash driver is enabled. flash_map switch its
dependency to this keyword.

So far, DT did not support the flash driver name.
Any flash-controller should have the appropriate
flash driver that should be identified by its name.
This path adds generic support for extract the description
from the flash-controller node,
adds implementation of this property for all nrf5x targets.

Some drivers doesn't implement flash API page layout extension
which is causing the application crash once the API was calling.
This patch introduce system termination for this in those drivers
which doesn't implement extension. This will help to discover this
problem early.
It is not done by preprocessor check because it is possible to have
enabled a driver which support and a driver which doesn't support
this API simultaneously.
Now FLASH_PAGE_LAYOUT configuration option is accessible only in case
that at last one driver which implements mentioned API is enabled.

Added an internal function to obtain the flash page layout in
run-length encoded format. The API is simple and allows the actual
public API implementations to be simple and maintainable.
This feature can be enabled by using the FLASH_PAGE_LAYOUT Kconfig
option. This API is required for the implementation of flash file
system.
Added a public API to get flash page information (size and start offset)
by offset within the flash and by index of the page.
Added a generic implementation of the internal flash_get_page_info API.
Added an additional public API call to get the total count of pages in
the flash memory and its generic implementation.

Rename the BT_CONTROLLER prefix used in all of the Kconfig variables
related to the Bluetooth controller to BT_CTLR.
Signed-off-by: Carles Cufi <carles.cufi@nordicsemi.no>
The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.
Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

The STM32L4x SoCs embeds a slightly different embedded flash controller
from the STM32F4x SoCs.
This particular controller has the following properties :
- Up to 2 512KiB banks divided in 2KiB pages
- Flash can be accessed in any sizes
- Flash must be written in 64bit aligned 64bit double-words
The drivers/flash/flash_stm32f4x.c is refactored into a new common
drivers/flash/flash_stm32.c and drivers/flash/flash_stm32l4x.c is
created with the STM32L4x specific functions.
To ease the refactoring and keep common functions, the STM32L4x flash
headers are slightly modified to match the hardware reference naming
and solve compilation issues.

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.

This KSDK flash shim driver supports the device in the FRDM K64F
platform (enabled with this commit).
WARNING: the driver disables the system interrupts for potentially
long periods of time. This is required to avoid Read-While-Write
issues since most platforms run in XIP mode.

Calls to flash write or erase operations can get preempted
in the middle of the API call if a concurrent call (from
other fiber or task) to the same API is made. The patch ensures
concurrent API calls from other fiber/task is put on hold until
the current operation is completed.
The mechanism is by default not activated. To enable
it, the following flag needs to be defined:
CONFIG_SOC_FLASH_QMSI_API_REENTRANCY
