boards: gd32e507z_eval: add initial support
Add initial support for the GD32E507Z-EVAL board. Only basic peripherals are enabled for now: - UART - GPIO (LEDs, keys) - PWM Others, e.g. I2C, EEPROM, DAC, etc. require further testing and likely some driver adjustments. Signed-off-by: Gerard Marull-Paretas <[email protected]>

Overview
7+
********
8+
9+
The GD32E507Z-EVAL board is a hardware platform that enables prototyping
10+
on GD32E507ZE Cortex-M33 High Performance MCU.
11+
12+
The GD32E507ZE features a single-core ARM Cortex-M33 MCU which can run up
13+
to 180 MHz with flash accesses zero wait states, 512kiB of Flash, 128kiB of
14+
SRAM and 112 GPIOs.

77+
Serial Port
78+
===========
79+
80+
The GD32E507Z-EVAL board has one serial communication port. The default port
81+
is USART0 with TX connected at PA9 and RX at PA10. USART0 is exposed as a
82+
virtual COM port via the J1 USB connector.
83+
84+
Programming and Debugging
85+
*************************
86+
87+
Before programming your board make sure to configure boot jumpers as
88+
follows:
89+
90+
- JP3/4: Select 2-3 for both (boot from user memory)
91+
92+
Using GD-Link or J-Link
93+
=======================
94+
95+
The board comes with an embedded GD-Link programmer. It can be used with pyOCD
96+
provided you install the necessary CMSIS-Pack:
97+
98+
.. code-block:: console
99+
100+
pyocd pack install gd32e507ze
101+
102+
J-Link can also be used to program the board using the JTAG interface exposed in
103+
the JP2 header.
104+
105+
#. Build the Zephyr kernel and the :ref:`hello_world` sample application:
106+
107+
.. zephyr-app-commands::
108+
:zephyr-app: samples/hello_world
109+
:board: gd32e507z_eval
110+
:goals: build
111+
:compact:
112+
113+
#. Run your favorite terminal program to listen for output. On Linux the
114+
terminal should be something like ``/dev/ttyUSB0``. For example:
115+
116+
.. code-block:: console
117+
118+
minicom -D /dev/ttyUSB0 -o
119+
120+
The -o option tells minicom not to send the modem initialization
121+
string. Connection should be configured as follows:
122+
123+
- Speed: 115200
124+
- Data: 8 bits
125+
- Parity: None
126+
- Stop bits: 1
127+
128+
#. To flash an image:
129+
130+
.. zephyr-app-commands::
131+
:zephyr-app: samples/hello_world
132+
:board: gd32e507z_eval
133+
:goals: flash
134+
:compact:
135+
136+
You should see "Hello World! gd32e507z_eval" in your terminal.
137+
138+
#. To debug an image:
139+
140+
.. zephyr-app-commands::
141+
:zephyr-app: samples/hello_world
142+
:board: gd32e507z_eval
