Enables the FlexSPI NOR flash driver, configures the FlexSPI pins, and
updates the board documentation accordingly on the mimxrt1064_evk.
Note that this SoC has two FlexSPI instances: one instance has an
in-package QSPI flash used for XIP; the other instance has a board-level
QSPI flash used for storage, not XIP. This patch enables the flash
driver on the non-XIP flash only.
Tested with:
- samples/subsys/fs/littlefs
- samples/drivers/flash_shell

Enables the FlexSPI flash driver on the i.MX RT SoC family and
configures the peripheral clocks accordingly. We are careful to only
configure the peripheral clocks if we are not executing in place from
the FlexSPI flash.

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.

Adds a hidden config symbol HAS_MCUX_FLEXSPI selected by NXP SoCs when
the FlexSPI peripheral is present. It will be used as a dependency for a
new FlexSPI flash driver to prevent users from accidentally enabling the
driver on platforms that don't have the necessary hardware.

This changes the timing functions to use TSC to gather
timing information instead of using the timer for
scheduling as it provides higher resolution for timing
information.

The strategy used in z_heap_aligned_alloc() was to allocate an extra
align-sized memory block for storing a pointer to the memory heap.
This is wasteful in terms of memory usage when alignment is larger
than a pointer width. A loop is needed to find the initial memory
start when freeing it which isn't optimal either.
Instead, let's have sys_heap_aligned_alloc() rewind a pointer after
it is aligned to make just enough room for storing our heap reference.
This way the heap reference is always located immediately before the
aligned memory and any unused memory is returned to the heap.
The rewind and alignment values may coincide in which case only
the alignment is necessary anyway.

There are platforms that have multiple states that maps to a specific
Zephyr power state. To accommodate this sort of situation this commit
adds an additional property to a power state that can be used by the
platform.
The power state now consists of two properties, a category and a
substate-id. The former property is the current power state.
