The pocketbeagle2 uses the main_uart6 as the debug console. To get debug
console prints at the R5 SPL stage, add the &main_uart6 to the R5 clk
and dev data so we can configure the uart as early as possible during
the bootup of the pocketbeagle2

From: Randolph Sapp <rs@ti.com>
Add initial board support for the PocketBeagle 2, based on Robert Nelson
and Bryan Brattlof's work. Unify all debug consoles to main_uart6. Use
DDR config v10.32 from our sysconfig tool [1] for Kingston's memory [2],
(4Gb Desnity with a CL of 11 and CWL of 9). Add support for the
SPL_TEXT_BASE config parameter. Ensure all files have a summary and SPDX
identifier.
Also, use board_get_usable_ram_top() to fixup our relocaddr since
otherwise the u-boot stack reservation will collide with the
wkup_r5fss0_core0_memory_region.

+AM62 Beagleboard.org PocketBeagle 2
+===================================
+
+Introduction:
+-------------
+
+BeagleBoard.org PocketBeagle 2 is an easy to use, affordable open source
+hardware single board computer based on the Texas Instruments AM625
+SoC.
+
+Further information can be found at:
+
+* Product Page: https://www.beagleboard.org/boards/pocketbeagle-2
+* Hardware documentation: https://openbeagle.org/pocketbeagle/pocketbeagle-2
+
+Boot Flow:
+----------
+Below is the pictorial representation of boot flow:
+
+.. image:: ../ti/img/boot_diagram_am62.svg
+ :alt: Boot flow diagram
+
+On this platform, 'TI Foundational Security' (TIFS) functions as the security
+enclave master while 'Device Manager' (DM), also known as the 'TISCI server' in
+"TI terminology", offers all the essential services. The A53 or M4F (Aux core)
+sends requests to TIFS/DM to accomplish these services, as illustrated in the
+diagram above.
+
+Sources:
+--------
+.. include:: ../ti/k3.rst

+
+Build procedure:
+----------------
+
+#. Setup the environment variables:

+ :end-before: .. am62x_evm_rst_include_end_build_steps
+
+Target Images
+-------------
+Copy these images to an SD card and boot:
+
+ * :file:`tiboot3.bin` from Cortex-R5 build.
+ * :file:`tispl.bin` and :file:`u-boot.img` from Cortex-A build
+
+Image formats
+-------------
+
+- :file:`tiboot3.bin`
+
+ .. image:: ../ti/img/multi_cert_tiboot3.bin.svg
+ :alt: tiboot3.bin image format
+
+- :file:`tispl.bin`
+
+ .. image:: ../ti/img/tifsstub_dm_tispl.bin.svg
+ :alt: tispl.bin image format
+
+Additional hardware for U-Boot development
+------------------------------------------
+
+* A Serial Console is critical for U-Boot development on the PocketBeagle 2. See
+ `PocketBeagle 2 serial console documentation`__.
+* uSD is the default, and a SD/MMC reader will be needed.
+* (optionally) JTAG is useful when working with very early stages of boot.
+
+.. __: https://docs.beagleboard.org/boards/pocketbeagle-2/03-design-and-specifications.html#serial-debug-port
+
+Default storage options
+-----------------------
+
+There is only one storage media option for the PocketBeagle 2, by default:
+
+* SD/MMC card interface
+
+Flash to uSD card
+-----------------
+
+If you choose to hand format your own bootable uSD card, be
+aware that it can be difficult. The following information
+may be helpful, but remember that it is only sometimes
+reliable, and partition options can cause issues. These
+can potentially help:
+
+* https://git.ti.com/cgit/arago-project/tisdk-setup-scripts/tree/create-sdcard.sh
+* https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD
+
+The simplest option is to start with a standard distribution
+image like those in `BeagleBoard.org Distros Page
+<https://www.beagleboard.org/distros>`_ and download a disk image for
+PocketBeagle 2. Pick a 16GB+ uSD card to be on the safer side.
+
+With an SD/MMC Card reader and `Balena Etcher
+<https://etcher.balena.io/>`_, having a functional setup in minutes is
+a trivial matter, and it works on almost all host operating systems.
+
+Updating U-Boot is a matter of copying the :file:`tiboot3.bin`,
+:file:`tispl.bin` and :file:`u-boot.img` to the "BOOT" partition of the uSD
+card. Remember to sync and unmount (or Eject - depending on the Operating
+System) the uSD card prior to physically removing from SD card reader.
+
+Also see following section on switch setting used for booting using
+uSD card.
+
+.. note::
+
+ If you are frequently working with uSD cards, you might find the
+ following useful:
+
+ * `USB-SD-Mux <https://www.linux-automation.com/en/products/usb-sd-mux.html>`_
+ * `SD-Wire <https://wiki.tizen.org/SDWire>`_
+
+LED patterns during boot
+------------------------
+
+.. list-table:: USR LED status indication
+ :widths: 16 16
+ :header-rows: 1
+
+ * - USR LEDs (1234)
+ - Indicates
+
+ * - 0000
+ - Boot failure or R5 image not started up
+
+ * - 1111
+ - A53 SPL/U-boot has started up
+
+ * - 1010
+ - OS boot process has been initiated
+
+ * - 0101
+ - OS boot process failed and drops to U-Boot shell
+
+.. note::
+
+ In the table above, 0 indicates LED switched off and 1 indicates LED
+ switched ON.
+
+.. warning::
+
+ If the "red" power LED is not glowing, the system power supply is not
+ functional. Please refer to the `PocketBeagle 2 documentation
+ <https://docs.beagleboard.org/boards/pocketbeagle-2/>`_ for further
+ information.
+
+A53 SPL DDR Memory Layout
+-------------------------
+
+.. include:: ../ti/am62x_sk.rst
+ :start-after: .. am62x_evm_rst_include_start_ddr_mem_layout
+ :end-before: .. am62x_evm_rst_include_end_ddr_mem_layout
+
+Switch Setting for Boot Mode
+----------------------------
+
+The boot time option is configured via "USR" button on the board. See the
+`PocketBeagle 2 Schematics
+<https://git.beagleboard.org/pocketbeagle/pocketbeagle-2/-/blob/main/pocketbeagle2_sch.pdf>`_
+and the `PocketBeagle 2 documentation on Boot Modes
+<https://docs.beagleboard.org/boards/pocketbeagle-2/03-design-and-specifications.html#boot-modes>`_
+for details.
+
+.. list-table:: Boot Modes
+ :widths: 16 16 16
+ :header-rows: 1
+
+ * - USR Button Status
+ - Primary Boot
+ - Secondary Boot
+
+ * - Not Pressed
+ - uSD
+ - USB Device Firmware Upgrade (DFU) mode
+
+ * - Pressed
+ - uSD
+ - UART
+
+To switch boot modes, hold the "USR" button while powering on the device with a
+USB type C power supply. Release the button when the red power LED lights up.
+
+DFU based boot
+--------------
+
+To boot the board over DFU, ensure there is no SD card inserted with a
+bootloader. After power-on the build artifacts needs to be uploaded one by one
+with a tool like dfu-util.
+
+.. include:: ../ti/am62x_sk.rst
+ :start-after: .. am62x_evm_rst_include_start_dfu_boot
+ :end-before: .. am62x_evm_rst_include_end_dfu_boot
+
+Debugging U-Boot
+----------------
+
+See :ref:`Common Debugging environment - OpenOCD <k3_rst_refer_openocd>`: for
+detailed setup and debugging information.
+
+.. warning::
+
+ **OpenOCD support since**: v0.12.0
+
+ If the default package version of OpenOCD in your development
+ environment's distribution needs to be updated, it might be necessary to
+ build OpenOCD from the source.
+
+.. include:: ../ti/k3.rst
+ :start-after: .. k3_rst_include_start_openocd_connect_tag_connect
+ :end-before: .. k3_rst_include_end_openocd_connect_tag_connect
+
+.. include:: ../ti/k3.rst
+ :start-after: .. k3_rst_include_start_openocd_cfg_external_intro
+ :end-before: .. k3_rst_include_end_openocd_cfg_external_intro
+
+For example, with the PocketBeagle 2 (AM62X platform), the
+:file:`openocd_connect.cfg` would look like:
+
+.. code-block:: tcl
+
+ # TUMPA example:
+ # http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_User's_Manual
+ source [find interface/ftdi/tumpa.cfg]
+
+ transport select jtag
+
+ # default JTAG configuration has only SRST and no TRST
+ reset_config srst_only srst_push_pull
+
+ # delay after SRST goes inactive
+ adapter srst delay 20
+
+ if { ![info exists SOC] } {
+ # Set the SoC of interest
+ set SOC am625
+ }
+
+ source [find target/ti_k3.cfg]
+
+ ftdi tdo_sample_edge falling
+
+ # Speeds for FT2232H are in multiples of 2, and 32MHz is tops
+ # max speed we seem to achieve is ~20MHz.. so we pick 16MHz
+ adapter speed 16000

Take Phytec's current DDR fixup functions and utilize them to
dynamically adjust for variants in the pocketbeagle2. There are
currently 3 skews, two of which are both 512MB with the same memory
configuration, and one which is 1GB using the same CWL and CL settings
but a modified density [1].
Based off of Bryan Brattlof's patch [2].

Just thinking out loud here, but maybe we shouldn't take this patch. The
industrial version, on top of having more memory, also has eMMC. That already
mandates a new device tree and configuration if people are going to use it as a
boot method.
Then again, maybe it's convenient for the users who don't care about eMMC? I
dunno. Seems odd either way.

Since it's technically a different board altogether and not just PB2 w/
extra DDR. I think it might be better if it had a separate DT and we can
decide the correct one based on the EEPROM at runtime using
SPL_MULTI_DTB_FIT which would allow us to still have a single defconfig
in U-Boot.

Syncing some internal comments here:
Zephyr and Jason Kridner apparently agree with me here. They treat the device as
a separate model: https://github.com/zephyrproject-rtos/zephyr/pull/106680
To cite Bryan Brattlof:
I don't think the R5 has the space to switch-out the DT like this during
bootup. it would need to be another build
Sounds like we'll have to upstream a separate dt and defconfig then. I'll play
around with this a little on my end before submitting another revision. Suppose
the dt will have to go to the kernel first so it'll be a little bit.

Sorry Randolph, I've been buried in emails. Thanks for syncing the
threads together.
My only worry here is having different builds for each flavor of the PB2
will complicate things for people who don't care about the BSP layers.
If all we're worried about is checking if the MMC is populated and which
DDR to setup before we hand things over to Linux then in my opinion is
this approach is better. Linux shouldn't care about these things.
We do have some space we can reclaim in the R5 SPL build but I seriously
doubt swapping out the DT on the fly like we're suggesting will work for
the R5 SPL. The only hope we have to unify the bootloaders for all PB2s
is going to be with this approach.

From: Randolph Sapp <rs@ti.com>
Add support for EFI capsules for this device. One large caveat is that
the partition holding boot binaries cannot be the ESP partition due to
the following ROM limitations.
- The boot disk must be MBR
- The boot partition must be labeled 0x0c with a boot flag
A separate ESP partition should be provided for EFI capabilities.

v3:
- Remove unnecessary dfu_alt_info_ram variable

Hi Randolph, all,
I tested this together with the ECDSA patch series v8, on top of the
current u-boot master.
I built a signed FIT image with Linux v7.1, target load address
0x84000000 and device tree address 0x83000000. This did not clash with
the $loadaddr of 0x82000000; the kernel address 0x81000000 would cause
u-boot to crash and reboot.
The kernel booted fine, but the
https://www.beagleboard.org/distros/pocketbeagle-2-debian-13-5-2026-05-19-minimal-v6-12-x-ti
user space would fail to start up ZRAM. I guess it's simply because I
did not make any kernel modules available yet. I was able to get into
the login screen and shut down the system nevertheless.
My ultimate goal is to set up trusted boot on top of TF-A. The
PocketBeagle 2 is a convenient development platform.
With best regards,
Marko
