boards: nxp: imx95_evk_15x15: add i.MX 95 15x15 LPDDR4x EVK variant
Add initial support for i.MX 95 15x15 LPDDR4x EVK board. This board uses the i.MX 95 15x15 SoC that shares many similarities to the already supported i.MX 95 19x19 SoC used for the i.MX 95 19x19 LPDDR5 EVK. This enables Zephyr to boot and run on the i.MX 95 15x15 EVK and provides a foundation for further peripheral enablement and application development. Signed-off-by: Aziz Sellami <[email protected]>

Overview
4+
********
5+
6+
The i.MX95 EVK (IMX95LP4XEVK-15) board is a platform designed to show the
7+
most commonly used features of the i.MX 95 applications processor.
8+
It is an entry-level development board, which helps developers to get familiar
9+
with the processor before investing a large amount of resources in more
10+
specific designs. The i.MX 95 device on the board comes in a compact
11+
15 x 15 mm package.
12+
13+

Supported Features
61+
==================
62+
63+
.. zephyr:board-supported-hw::
64+
65+
System Clock
66+
------------
67+
68+
This board configuration uses a system clock frequency of 24 MHz for Cortex-A55.
69+
Cortex-A55 Core runs up to 1.8 GHz.
70+
71+
Serial Port
72+
-----------
73+
74+
This board configuration uses a single serial communication channel with the
75+
CPU's UART1 for Cortex-A55.
76+
77+
Programming and Debugging (A55)
78+
*******************************
79+
80+
Use this configuration to run basic Zephyr applications and kernel tests,
81+
for example, with the :zephyr:code-sample:`synchronization` sample:
82+
83+
1. Build and run the Non-SMP application
84+
85+
.. zephyr-app-commands::
86+
:zephyr-app: samples/synchronization
87+
:host-os: unix
88+
:board: imx95_evk_15x15/mimx9596/a55
89+
:goals: build
90+
91+
This will build an image (zephyr.bin) with the synchronization sample app.
92+
93+
Copy the compiled ``zephyr.bin`` to the first FAT partition of the SD card and
94+
plug the SD card into the board. Power it up and stop the u-boot execution at
95+
prompt.
96+
97+
Use U-Boot to load and kick zephyr.bin to Cortex-A55 Core1:
98+
99+
.. code-block:: console
100+
101+
fatload mmc 1:1 0xd0000000 zephyr.bin; dcache flush; icache flush; cpu 1 release 0xd0000000
102+
103+
104+
Or use the following command to kick zephyr.bin to Cortex-A55 Core0:
105+
106+
.. code-block:: console
107+
108+
fatload mmc 1:1 0xd0000000 zephyr.bin; dcache flush; icache flush; go 0xd0000000
109+
110+
111+
It will display the following console output:
112+
113+
.. code-block:: console
114+
115+
