[nrf fromlist] boards: nordic: Add nRF93M1 DK board
Add build targets for nRF93M1 DK board which includes nRF54L15 as a host MCU. Bulk of the board definitions are copied from nRF54L15DK. Main differences: * The console UART is changed to uart20 as uart30 is routed to modem * Few GPIO hogs to control the modem and UART switches * nPM1300 PMIC set up to enable various voltages on board Signed-off-by: Seppo Takalo <seppo.takalo@nordicsemi.no> Upstream PR #: 106289

Overview
4+
********
5+
6+
.. note::
7+
You can find more information about the nRF93M1 module on the `nRF93M1 website`_.
8+
9+
The nRF93M1 Development Kit (DK) is a single-board development kit for evaluation
10+
and development of LTE Cat 1 bis IoT applications using the nRF93M1 cellular module.
11+
The board integrates the Nordic Semiconductor nRF54L15 as the host MCU and the
12+
nRF93M1 as the LTE Cat 1 bis modem module, connected over UART.

Hardware
21+
********
22+
23+
The nRF93M1 DK includes the following hardware components:
24+
25+
* nRF54L15 host MCU (ARM Cortex-M33 application core + RISC-V FLPR core)
26+
* nRF93M1 LTE Cat 1 bis modem module
27+
* nPM1300 PMIC with battery charger
28+
* USB-C connector for programming, debugging and power

The nRF93M1 modem module is connected to the nRF54L15 host MCU over UART with
55+
hardware flow control (``uart30``). The following control signals are available:
56+
57+
* DC switch enable = P1.1
58+
* Power key = P1.13
59+
* Reset = P1.12

Programming and Debugging
64+
*************************
65+
66+
.. zephyr:board-supported-runners::
67+
68+
Applications for the ``nrf93m1dk/nrf54l15/cpuapp`` board target can be
69+
built, flashed, and debugged in the usual way. See
70+
:ref:`build_an_application` and :ref:`application_run` for more details on
71+
building and running.
72+
73+
Flashing
74+
========
75+
76+
As an example, this section shows how to build and flash the :zephyr:code-sample:`hello_world`
77+
application.
78+
79+
Follow the instructions in the :ref:`nordic_segger` page to install
80+
and configure all the necessary software. Further information can be
81+
found in :ref:`nordic_segger_flashing`.
82+
83+
To build and program the sample to the nRF93M1 DK, complete the following steps:
84+
85+
First, connect the nRF93M1 DK to your computer using the USB1 port on the DK.
86+
Next, build the sample by running the following command:
87+
88+
.. zephyr-app-commands::
89+
:zephyr-app: samples/hello_world
90+
:board: nrf93m1dk/nrf54l15/cpuapp
91+
:goals: build flash
92+
93+
Debugging
94+
=========
95+
96+
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
97+
Segger IC.
