Add a weak definition for board_setup_dest_addr, as a way for specific
boards to override the gd->relocaddr address before the relocation
actually occurs.

board_get_usable_ram_top() can be used instead.

It *could*. Just felt a little weird to artificially restrict the usable memory
because the stack just barely runs into one of our reserved regions long enough
to break a dt reserved-memory allocation.
Initially this was proposed because there are multiple runtimes with their own
allocation techniques that could potentially take advantage of that space. If
it's still preferable to use board_get_usable_ram_top though I will change it.

I am not sure I understand this without an example. We always relocate
to ram_top for now and that's why that function exists. I've already
started to clean up the relocations a bit [0]. I don't want to add
more functions to tweak the reloc address unless necessary. Generally
speaking the reloc address should not be board specific at all imho.
If there are areas that we shouldn't use they need to be described in
the DT and the core code should look at that. I am ok keeping one
function to change this, but not more. We also have
arch_setup_dest_addr() which isactually board specific (look at
arch/powerpc/lib/stack.c which is the only place we define it).

Alright, I'll add a little information about the specific predicament we're in
because of this board. Our ram_top is something like ~26MB away from a reserved
memory region defined in device tree. After the relocation, before we can
reserve the dt regions, we actually creep past 26MB of utilization. This makes
the dt reservation fail in the LMB path, but later the utilization retracts.
This lead me to find that some useful warnings were disabled [1] and other odd
things were occurring as a result.
We can't even parse the dt without first reaching into one of the reserved
regions. With everything using physical addresses we can't really relocate the
active reservations to avoid this.
To be clear, I don't even like the solution I proposed here because it requires
coordination between a device tree and a local configuration.
There just isn't enough wiggle room here when u-boot doesn't have a real stack
size limit. We can't fully plan out a memory map ahead of time nor can we
account for this at runtime. Please inform me if I'm missing something here,
still fairly new to the way u-boot handles things.
Thanks for look at this Ilias. Hard to get these kind of discussions otherwise.

I think the reality is that we will always have 'special' cases and
we'll need a board function that tweaks the reloc address. But that
should be the vast minority. I don't think we can solve this with a
single commit. But cleaning up the core code will give as a pretty
good idea of how many 'special' cases we actually have.

Ok so from what I read board_get_usable_ram_top() does solve your
problem, right?
I suggest you just define that and revisit the whole thing once I
clean up a bit more.
For example, I don't see why we need arch_setup_dest_addr() and we
just can't define board_get_usable_ram_top() for the affected ppc
boards.

YW, I do care about abstracting this nicely and reducing the board
specific code So if you have more of these cases feel free to cc me.

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

Cc: u-boot
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_setup_dest_addr 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:

+
+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].

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.

Hi Randolph, all,
>Add initial board support for the PocketBeagle 2 from BeagleBoard.org.
Thank you, this is very small, and best of all, it works for me, on top
of master d57ea0d9edf5e5babffd280f7352f23a33a00948 from last Sunday. I
slightly adjusted the board_setup_dest_addr() injection in the first
patch in order to resolve a code conflict:
@@ -356,6 +361,8 @@ static int setup_dest_addr(void)
gd->relocaddr = gd->ram_top;
debug("Ram top: %08llX\n", (unsigned long long)gd->ram_top);
+ if (board_setup_dest_addr()) return board_setup_dest_addr();
+
return arch_setup_dest_addr();
}
I successfully booted this together with a version of the software ECDSA
patch, but did not try to load a signed FIT image yet.
Marko
