boards/arm: add support for imx95-evk m7 core
- Add support for the IMX95LPD5EVK-19 evaluation kit (M7 core only) - Firmware can be executed from ITCM, DDR or NOR flash - configurations: 'nsh' A minimal configuration that only enables nsh shell on a UART 'rpmsg' This configuration is similar to nsh but in addition it offers the Remote Processing Messaging (RPMsg) service to enable heterogeneous inter-core communication.

IMX95LPD5EVK-19
3+
===============
4+
5+
The IMX95LPD5EVK-19 board is a platform designed to show the most commonly
6+
used features of the i.MX 95 automotive applications processor.
7+
8+
Features
9+
========
10+
11+
- Multicore Processing [1]_
12+
- 1x Arm Cortex-M7
13+
- 6x Arm Cortex-A55 multicore complex
14+
- 1x Arm Cortex-M33
15+
- Memory
16+
- On-Chip Memory
17+
- 1376kB SRAM (ECC)
18+
- External Memory
19+
- Up to 6.4GT/s x32 LPDDR5/LPDDR4X (with Inline ECC & Inline Encrpytion)
20+
- 1x Octal SPI, including support for SPI NOR and SPI NAND memories
21+
- Connectivity
22+
- CAN FD
23+
- UART/USART/Profibus, I²C, SPI
24+
- Messaging Units (MU) to support IPC between heterogeneous cores
25+
26+
.. [1] NuttX is currently supported exclusively on the Cortex-M7 core of the
27+
i.MX95
28+
29+
Serial Console
30+
==============
31+
32+
The IMX95LPD5EVK-19 board features a high-speed USB-to-UART/MPSSE device,
33+
FT4232H (U70) that provides a debug interface for the i.MX95 processor through
34+
the USB type-C connector (J31). The device acts as a bridge to enable
35+
communication between the target processor and the host computer, which
36+
connects to the USB connector (J31) through a USB cable.
37+
38+
Channel A is used as UART port to provide USB-to-UART option for debugging the
39+
Arm Cortex-M7 core of the i.MX 95 processor (default option).
40+
41+
J-Link External Debug Probe
42+
===========================
43+
44+
The IMX95LPD5EVK-19 board provides a 2x5-pin Samtec FTSH-105-01-L-DV-K header
45+
(J30) for connecting a JTAG debugger (external JTAG) for debugging the i.MX95
46+
processor. The FT4234H JTAG provides the remote debug option for the i.MX95
47+
processor.
48+
49+
Configurations
50+
==============
51+
52+
nsh
53+
---
54+
55+
Configures the NuttShell (nsh) located at examples/nsh. This NSH
56+
configuration is focused on low level, command-line driver testing. Built-in
57+
applications are supported, but none are enabled. This configuration does not
58+
support a network.
59+
60+
This configuration can be used in combination with the default sd-card image
61+
that is shipped with the EVK.
62+
63+
rpmsg
64+
-----
65+
66+
This configuration is similar to nsh but in addition it offers the Remote
67+
Processing Messaging (RPMsg) service to enable heterogeneous inter-core
68+
communication. A virtual UART (CONFIG_RPMSG_UART) is made available on which
69+
an OS running on the A55 cores can connect. There is also an option to use
70+
the filesystem client feature in which a remote directory can be mounted to
71+
a local directory (CONFIG_FS_RPMSGFS).
72+
73+
The rpmsg configuration executes the code from DDR since its code memory
74+
footprint is bigger than the ITCM size. In the case of using the default
75+
sd-card image from the EVK, adaptations are needed on the software running on
76+
the M33 and A55 cores.
77+
78+
- `System Manager <https://github.com/nxp-imx/imx-sm>`_ (M33) should give
79+
the M7 access to the DDR region
80+
- `linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) should reserve
81+
the DDR region by specifying it in the device tree so linux won't make
82+
use of it
83+
- `linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) needs the
84+
NuttX compatible rpmsg_tty and rpmsg_fs drivers. See `dev mailing list
85+
<https://www.mail-archive.com/[email protected]/msg12112.html>`_
