The i.MX 6SoloX SoC is a hybrid multi-core processor composed by one
Cortex A9 core and one Cortex M4 core.
Zephyr was ported to run on the M4 core. In a later release, it will
also communicate with the A9 core (running Linux) via RPMsg.
The low level drivers come from NXP FreeRTOS BSP and are located at
ext/hal/nxp/imx. More details can be found at ext/hal/nxp/imx/README
The A9 core is responsible to load the M4 binary application into the
RAM, put the M4 in reset, set the M4 Program Counter and Stack Pointer,
and get the M4 out of reset.
The A9 can perform these steps at bootloader level after the Linux
system has booted.

This code component is used to add Zephyr support on iMX6SX
processors, exclusively on Cortex M4 core, and to speed up the
development process it was decided to have it based on NXP FreeRTOS BSP
implementation.
The i.MX FreeRTOS BSP is split into separate downloadable packages,
based on SoC. The packages share most of the peripheral driver files
and here they are combined together.
The source code was imported from the following folders:
FreeRTOS_BSP_1.0.1_iMX6SX/platform/drivers
FreeRTOS_BSP_1.0.1_iMX6SX/platform/devices
This source code depends on headers and sources from zephyr:

Bool symbols implicitly default to 'n'.
A 'default n' could make sense e.g. in a Kconfig.defconfig file, if you
wanted to override a 'default y' on the base definition of the symbol,
but it doesn't seem to be used like that on any of these symbols.

Updates nrfx to the recently released version.
This version introduces a new HAL for the RADIO peripheral (contained
in the "nrf_radio.h" file) and this HAL replaces the one temporarily
copied to the "nrfx/hal" folder in the Zephyr source tree (see commit
619790a9bcb3a6fea7a91af24007eba6404c1a2b). The nRF 802.15.4 radio
driver ("nrf_drv_radio802154.c") is updated accordingly to reflect
the changes between these two RADIO HAL implementations.

The STM32L4x2 SoCs need to control the isolation of the USB features
from VDDUSB. This is done through the PWR_CR2 bit USV. The STM32L4 HAL
in stm32l4xx_ll_pwr.h wrongly checks for the PWR_CR2_PVME1 bit, which
is only available on Cat. 3 devices. Replace the check by PWR_CR2_USV

When we import open-amp we removed the apps dir to reduce the amount
of code imported.
Purpose:
IPC layer that implements rpmsg communication between cores.
Description:
This repository is the home for the Open Asymmetric Multi Processing
(OpenAMP) framework project. The OpenAMP framework provides software
components that enable development of software applications for
Asymmetric Multiprocessing (AMP) systems. The framework provides the
following key capabilities.
* Provides Life Cycle Management, and Inter Processor Communication
capabilities for management of remote compute resources and their
associated software contexts.
* Provides a stand alone library usable with RTOS and Baremetal software
environments
* Compatibility with upstream Linux remoteproc and rpmsg components
* Following AMP configurations supported:
a. Linux master/Generic(Baremetal) remote
b. Generic(Baremetal) master/Linux remote
* Proxy infrastructure and supplied demos showcase ability of proxy on
master to handle printf, scanf, open, close, read, write calls from
Bare metal based remote contexts.
Dependencies:
libmetal (https://github.com/OpenAMP/libmetal) - provides HAL layer
between OpenAMP and RTOS or OS environment.

Purpose:
HAL abstraction layer used by open-amp
Description:
Libmetal provides common user APIs to access devices, handle device
interrupts and request memory across the following operating
environments:
* Linux user space (based on UIO and VFIO support in the kernel)
* RTOS (with and without virtual memory)
* Bare-metal environments
Dependencies:
Depends on Zephyr itself as it utilizes Zephyr's APIs to provide an
abstraction to open-amp.

We have been combining imported mcux drivers into a flattened directory
structure to maximize driver reuse, but the introduction of additional
nxp soc families (lpc and imx) to zephyr has introduced driver naming
conflicts. This caused us to rename and modify imported files, such as
fsl_gpio.c/h, to make them unique across all three nxp soc families.
This makes updating the the mcux drivers complicated, especially for the
lpc family.
Reoganize the mcux drivers into soc family subfolders, so we can just
copy all the drivers from an mcux distribution (which is done on an
soc-basis) into the appropriate soc family folder. Undo all of the
naming changes that occurred when lpc and imx drivers were originally
imported. Undo the accidental squashing of the kinetis watchdog and dcdc
drivers that occurred when the imx drivers were introduced.
The drawback to this approach is that we have duplicate files when the
same hw ip modules exist in multiple soc families, however there are
only few cases where this occurs, such as fsl_lpuart and fsl_trng.
