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>

Platform-specific options should be in their own Kconfig files to be consistent and to not pollute the common configuration. To this end we move the mcux options into it's own file.

Enables the MCUX flash shim driver.
WARNING: This driver will disable the system interrupts for
the duration of the flash erase/write operations. This will
have an impact on the overall system performance - whether
this is acceptable or not will depend on the use case.
drivers: soc_flash_mcux check before reading LPC55xxx SoCs don't allow reading erased areas, the flash memory controller (FMC) will trigger an ECC error for that area. To prevent reading unwritten areas the low level FMC command of margin checking is used, this will fail if the area to be read is not correctly written (margin_check) or area is erased (blank_check). In the case of an erased page, we return dummy data so the application can program that area. Signed-off-by: Andrei Gansari <andrei.gansari@nxp.com>

help
Do a margin check flash command before reading an area.
This feature prevents erroneous/forbidden reading. Some ECC enabled
devices will crash when reading an erased or wrongly programmed area.

drivers: flash: Introduce i.MX RT FlexSPI driver Introduces a new flash driver for the FlexSPI peripheral on i.MX RT SoCs. The hardware provides a flexible sequence engine (LUT) that supports various types of external devices, including serial NOR flash, serial NAND flash, HyperBus (HyperFlash/HyperRAM), and FPGAs. It supports up to four connected devices in single/dual/quad/octal modes and provides memory-mapped read/write access to these devices through the AHB bus. The driver implementation consists of a shared controller for each FlexSPI peripheral instance, and protocol-specific device drivers for each external device. The controller provides a private interface for multiple devices to access the FlexSPI peripheral registers. FlexSPI devices provide the public flash driver interface to applications or subsystems like storage or flash file systems; they also provide protocol-specific LUT sequences to the controller. Currently the only device type supported is QSPI NOR flash, but other types like HyperFlash will be added later. XIP is not yet supported, as this requires additional work to relocate code to RAM and managing interrupts. Signed-off-by: Maureen Helm <maureen.helm@nxp.com>
