boards: arm: Add ip_k66f board support

Browse source 
IP ethernet switch board includes K66F MCU from NXP
and Micrel/Microchip KSZ8794CNX switch. Board support
includes basic GPIO LED and common functions.

Switch function needs support either based on DSA or
relative feature in Zephyr which is tracked with issue
22061.

SEGGER IP Switch Board
######################
Overview
********
The Segger IP Switch Board is a Evaluation board based on NXP Kinetis K66 MCU.
It comes with Micrel/Microchip KSZ8794CNX integrated 4-port 10/100 managed
Ethernet switch with Gigabit RGMII/MII/RMII interface.
- KSZ8794CNX enables evaluation for switch functions
- On-board debug probe J-Link-OB for programming
.. image:: ./ip_k66f.png

:align: center
:alt: IP-K66F
Hardware
********
- MK66FN2M0VMD18 MCU (180 MHz, 2 MB flash memory, 256 KB RAM, low-power,
crystal-less USB
- Dual role USB interface with micro-B USB connector
- 2 User LED
- On-board debug probe J-Link-OB for programming
- Micrel/Microchip Ethernet Switch KSZ8794CNX with 3 RJ45 connectors
For more information about the K66F SoC and IP-K66F board:
- `K66F Website`_
- `K66F Datasheet`_
- `K66F Reference Manual`_

- `IP-K66F User Guide`_
- `IP-K66F Schematics`_
Supported Features
==================
The ip_k66f board configuration supports the following hardware features:
+-----------+------------+-------------------------------------+
| Interface | Controller | Driver/Component |
+===========+============+=====================================+
| NVIC | on-chip | nested vector interrupt controller |
+-----------+------------+-------------------------------------+
| SYSTICK | on-chip | systick |
+-----------+------------+-------------------------------------+
| PINMUX | on-chip | pinmux |
+-----------+------------+-------------------------------------+
| GPIO | on-chip | gpio |
+-----------+------------+-------------------------------------+
| WATCHDOG | on-chip | watchdog |
+-----------+------------+-------------------------------------+
| FLASH | on-chip | soc flash |
+-----------+------------+-------------------------------------+
| RTC | on-chip | rtc |
+-----------+------------+-------------------------------------+
The default configuration can be found in the defconfig file:
``boards/arm/ip_k66f/ip_k66f_defconfig``
Micrel/Microchip KSZ8794CNX Ethernet Switch is not currently
supported.
Connections and IOs
===================
The K66F SoC has five pairs of pinmux/gpio controllers.
+-------+-----------------+---------------------------+
| Name | Function | Usage |
+=======+=================+===========================+
| PTA8 | GPIO | Red LED |
+-------+-----------------+---------------------------+
| PTA10 | GPIO | RED LED |
+-------+-----------------+---------------------------+
System Clock
============
The K66F SoC is configured to use the 12 MHz low gain crystal oscillator on the
board with the on-chip PLL to generate a 180 MHz system clock.
Serial Port
===========
The K66F SoC has six UARTs. None of them are used.
Programming and Debugging
*************************
Build and flash applications as usual (see :ref:`build_an_application` and
:ref:`application_run` for more details).
Configuring a Debug Probe
=========================
A debug probe is used for both flashing and debugging the board. This board is
configured by default to use the :ref:`opensda-jlink-onboard-debug-probe`.
:ref:`opensda-jlink-onboard-debug-probe`
--------------------------------------------------
Install the :ref:`jlink-debug-host-tools` and make sure they are in your search
path.
Follow the instructions in :ref:`opensda-jlink-onboard-debug-probe` to program
the `OpenSDA J-Link Generic Firmware for V3.2 Bootloader`_. Note that Segger
does provide an OpenSDA J-Link Board-Specific Firmware for this board, however
it is not compatible with the DAPLink bootloader.
The default flasher is ``jlink`` using the built-in SEGGER Jlink interface.
Flashing
========
Here is an example for the :ref:`blinky-sample` application.
.. zephyr-app-commands::
:zephyr-app: samples/basic/blinky
:board: ip_k66f
:goals: flash
Red LED0 should blink at 1 second delay.
Debugging
=========
Here is an example for the :ref:`blinky-sample` application.
.. zephyr-app-commands::
:zephyr-app: samples/basic/blinky
:board: ip_k66f
:goals: debug
Step through the application in your debugger.
