Stanislav Poboril 631eedd334 arch: Add imx6sx m4 soc support
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.

Diego Sueiro 346165b2e8 serial: Add imx uart driver shim
Adds a shim layer around the imx uart driver to adapt it to the Zephyr
serial interface.

Modem mode was introduce to control it as DCE and DTE and can be
configured in the device tree:
    modem-mode:
        type: int
        category: required
        description: Set the UART Port to modem mode 0 (dce) 1 (dte)
        generation: define

For now only the UART 2 was tested.

Diego Sueiro 3afc2b6c61 ext/hal/nxp/imx: Import the nxp imx7 freertos bsp
This code component is used to add Zephyr support on iMX7 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 source code was imported from the following folders:
    FreeRTOS_BSP_1.0.1_iMX7D/platform/drivers
    FreeRTOS_BSP_1.0.1_iMX7D/platform/devices

This source code depends on headers and sources from zephyr:
    ext/hal/cmsis
