This is a good point, not directly related to kconfig. Thank you. Ignore
this patch.

[PATCH] board: ti: am62x: Add variable device tree in env
Added variable default_device_tree that grabs from defconfig. Prevents
needing to change this variable in two locations if using a separate
device tree. In the future, it would be a good idea to remove this logic
completely, but this will help reduce complications.

+
+Debugging SPL in OpenOCD
+
+
+The following section demonstrates how to connect a board to OpenOCD and
+load the SPL symbols for debugging with a K3 generation device. For the
+guide below, users are expected to generate custom binaries, boot their
+board from an SD card and work with OpenOCD in a Linux environment. This
+guide uses the AM625-SK for device specific examples but can be extended
+to any K3 generation device.
+
+Step 1: Downloading OpenOCD
+---
+
+Download OpenOCD using the following command.
+
+.. code-block:: bash
+
+ sudo apt-get install openocd
+
+.. note::
+
+ OpenOCD version 0.12.0 is required to connect to the AM625-SK. Some
+ major GNU/Linux distros do not support version 0.12.0. Check the
+ version of OpenOCD with ``openocd -v``
+
+**For OpenOCD installations prior to version 0.12.0:**
+
+Clone the OpenOCD source code (https://openocd.org/).
+
+.. code-block:: bash
+
+ git clone https://git.code.sf.net/p/openocd/code openocd-code
+
+Move the required config files to the package installation of OpenOCD.
+
+.. code-block:: bash
+
+ cd {OpenOCD Source}
+ cp tcl/board/ti_am625evm.cfg /usr/local/share/openocd/scripts/board
+ cp tcl/target/ti_k3.cfg /usr/local/share/openocd/scripts/target
+
+Now you can move on to SK/EVM Setup to prepare your SK/EVM for debugging.
+
+Step 2: SK/EVM Setup
+
+
+Make the appropriate board cable connections.
+
+.. note::
+
+ Ensure that the BOOT MODE switches are set appropriately for an SD
+ Card boot (refer to the TRM for boot mode switch settings). For
+ AM62x devices, refer to :doc:`/board/ti/am62x_sk`.
+
+After connecting each of the cables from the figure above, run the
+following command to ensure that each connection is established.
+
+.. code-block:: bash
+
+ sudo dmesg | grep tty
+
+An output similar to the figure below should appear.
+
+::
+
+ [XX.XX] usb 1-5.3.2.2: FTDI USB Serial Device converter now
attached to ttyUSB0 <- Used for UART Flashing, UART boot, Linux Kernel,
U-Boot
+ [XX.XX] usb 1-5.3.2.2: FTDI USB Serial Device converter now
attached to ttyUSB1
+ [XX.XX] usb 1-5.3.2.2: FTDI USB Serial Device converter now
attached to ttyUSB2 <- Used for Console for DM R5F (WKUP R5F)
+ [XX.XX] usb 1-5.3.2.2: FTDI USB Serial Device converter now

+ [XX.XX] cdc_acm 1-5.3.1:1.0: ttyACM0: USB ACM device
+ [XX.XX] cdc_acm 1-5.3.1:1.3: ttyACM1: USB ACM device
+
+Open a serial connection with a baud rate of 115200 to view the kernel
+and U-Boot logs. Use the following command or a serial monitor of your
+choice.
+
+.. code-block:: bash
+
+ sudo picocom -b 115200 /dev/ttyUSB0
+
+Step 3: OpenOCD Debugging
+-
+
+Now that OpenOCD has been configured, launch an OpenOCD server with the
+following command.
+
+.. code-block:: bash
+
+ openocd -f board/ti_am625evm.cfg
+
+Below is an example of what the output of this command will print.

Introduce a minimal platform wakeup configuration for am62x devices.
These defconfigs are meant to serve as a foundation for custom boards to
build upon by only including necessary components to boot the device.
Defconfig fragments will be used to expand upon these base files.

[RFC PATCH 0/3] Minimal platform configuration
When someone attempts to bring up a custom board using TI SoCs (am62x in
this case), it often takes several days for someone to reduce the
current configuration from the TI EVM/SK boards to a configuration that
works for their board.
The goal of these changes is to allow for a minimal boot configuration
to exist within UBoot that someone can access directly in order to
test their boards for a sign of life before beginning development. This
is all done with the hope to increase ease of use and reduce the
upbringing process from several days to a few hours.
With the use of fragments, the base defconfigs reside in configs/ and
the config fragments reside in board/../
There is still quite a lot of board specific code inside board_init_f()
that will need attention later, however this series begins the process
of splitting the am62x's configs into a separate generic defconfig
everyone can use for new board wakeups with individual board/ti/*.config
fragments for each board varient.
