Merge patch series "Add PCIe Boot support for TI J784S4 SoC"
Siddharth Vadapalli <s-vadapalli@ti.com> says:
This series adds PCIe endpoint boot support for the TI J784S4 SoC.
Series is based on commit f9ffeec4bdc ("board: toradex: Make A53 get RAM
size from DT in K3 boards") of the master branch of U-Boot.
PCIe Boot Logs (J784S4-EVM running Linux as Root-Complex transfers
bootloaders to another J784S4-EVM configured for PCIe Boot):

PCIe Boot
|
||||
---------
|
||||
|
||||
The J784S4 SoC supports booting over PCIe, allowing the device to function
|
||||
as a PCIe endpoint and receive boot loader images from a PCIe Root Complex.
|
||||
The PCIe1 instance of PCIe is configured by Boot ROM for Endpoint Mode of
|
||||
operation. Hence, the PCIe Connector on the EVM corresponding to PCIe1
|
||||
should be utilized for PCIe Boot.
|
||||
|
||||
Hardware Setup
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
To boot the J784S4 EVM via PCIe, the following hardware setup is required:
|
||||
|
||||
1. Configure the boot mode switches on J784S4-EVM for PCIe boot:
|
||||
|
||||
.. code-block:: text
|
||||
|
||||
SW7: 01010000
|
||||
SW11: 10001000
|
||||
|
||||
2. Connect the J784S4-EVM (endpoint) to a PCIe Root Complex (e.g., x86 host)
|
||||
using a PCIe cable. Both boards should be powered off before making the
|
||||
connection.
|
||||
|
||||
Endpoint Configuration
|
||||
^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The following configuration options are enabled by default in
|
||||
``j784s4_evm_r5_defconfig`` and ``j784s4_evm_a72_defconfig``:
|
||||
|
||||
- ``CONFIG_SPL_PCI_DFU_BAR_SIZE``: Size of the PCIe BAR for DFU/boot image download
|
||||
- ``CONFIG_SPL_PCI_DFU_VENDOR_ID``: PCIe vendor ID advertised by the endpoint
|
||||
- ``CONFIG_SPL_PCI_DFU_DEVICE_ID``: PCIe device ID advertised by the endpoint
|
||||
- ``CONFIG_SPL_PCI_DFU_MAGIC_WORD``: Magic word written by Root Complex to signal image transfer completion
|
||||
- ``CONFIG_SPL_PCI_DFU_BOOT_PHASE``: Current boot phase indicator for Root Complex
|
||||
|
||||
By default, PCIe Root Complex mode is enabled in the device tree. For PCIe Boot,
|
||||
build the Bootloaders with the following content added to k3-j784s4-evm-u-boot.dtsi:
|
||||
|

PCIe Boot Procedure
|
||||
^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The following steps describe the process of booting J784S4-EVM over PCIe:
|
||||
|
||||
1. Compile the sample host program (provided after this section):
|
||||
|
||||
.. prompt:: bash
|
||||
|
||||
gcc -o pcie_boot_util pcie_boot_util.c
|
||||
|
||||
2. Power on the J784S4-EVM (endpoint) after configuring boot mode switches
|
||||
for PCIe Boot.
|
||||
|
||||
3. Copy the compiled sample host program (pcie_boot_util) and the bootloader
|
||||
images to the Root Complex. Check PCIe enumeration on Root Complex to ensure
|
||||
that the J784S4 EVM shows up as the PCIe Endpoint:
|
||||
|
||||
.. prompt:: bash
|
||||
|
||||
lspci
|
||||
|
||||
The endpoint will appear as a RAM device or with multiple functions:
|
||||
|
||||
.. code-block:: text
|
||||
|
||||
0000:00:00.0 PCI bridge: Texas Instruments Device b012
|
||||
0000:01:00.0 RAM memory: Texas Instruments Device b012
|
||||
0000:01:00.1 Non-VGA unclassified device: Texas Instruments Device 0100
|
||||
0000:01:00.2 Non-VGA unclassified device: Texas Instruments Device 0100
|
||||
|
||||
4. Copy ``tiboot3.bin`` to the endpoint. Use ``lspci -vv`` to identify the BAR
|
||||
address:
|
||||
|
||||
.. prompt:: bash
|
||||
|
||||
sudo ./pcie_boot_util 0x4007100000 tiboot3.bin
|
||||
|
||||
The sample program automatically writes the image start address to
|
||||
``0x41CF3FE0`` and the magic word ``0xB17CEAD9`` to ``0x41CF3FE4``.
|
||||
|
||||
5. After ``tiboot3.bin`` is processed, the PCIe link will go down briefly.
|
||||
Remove the PCIe device and rescan the bus:
|
||||
|
||||
.. prompt:: bash
|
||||
|
||||
echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
|
||||
echo 1 > /sys/bus/pci/devices/0000\:00\:00.0/rescan
|
||||
lspci
|
||||
|
||||
The enumeration will change to something similar:
|
||||
|
||||
.. code-block:: text
|
||||
|
||||
0000:00:00.0 PCI bridge: Texas Instruments Device b012
|
||||
0000:01:00.0 RAM memory: Texas Instruments Device b010 (rev dc)
|
||||
|
||||
.. note::
|
||||
|
||||
When the Root-Complex enumerates the PCIe Endpoint after a 'remove-rescan' sequence,
|
||||
it is possible that the 'BAR' appears 'disabled'. If so, writing to the BAR via the
|
||||
'pcie_boot_util' to transfer the bootloader image will have no effect. In such cases,
|
||||
run 'setpci -s 0000:01:00.0 COMMAND=0x02' on the Root-Complex after enumeration
|
||||
(with appropriate DOMAIN:BUS:DEVICE.FUNCTION corresponding to the Endpoint) to enable
|
||||
the BAR.
|
||||
|
||||
6. Copy ``tispl.bin`` to the new BAR address (use ``lspci -vv`` to find):
|
||||
|
||||
.. prompt:: bash
|
||||
|
||||
sudo ./pcie_boot_util 0x4000400000 tispl.bin
|
||||
|
||||
7. After ``tispl.bin`` is processed, the PCIe link will go down again. Remove
|
||||
and rescan the PCIe device:
|
||||
|
||||
.. prompt:: bash
|
||||
|
||||
echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
|
||||
echo 1 > /sys/bus/pci/devices/0000\:00\:00.0/rescan
|
||||
|
||||
8. Copy ``u-boot.img``:
|
||||
|
||||
.. prompt:: bash
|
||||
|
||||
sudo ./pcie_boot_util 0x4000400000 u-boot.img
|
||||
|
||||
9. After ``u-boot.img`` is successfully loaded, the boot process is complete
|
||||
and endpoint should boot till U-Boot prompt.
|
||||
|
||||
.. note::
|
||||
|
||||
During the boot process, "PCIe LINK DOWN" messages might appear in kernel
|
||||
logs. This is expected as the endpoint resets and re-initializes the PCIe
|
||||
link after processing each boot stage.
|
||||
|
||||
Sample Host Program
|
||||
^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The following C program can be used on the Root Complex to copy bootloader images
|
||||
to the J784S4 endpoint:
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
#include <stdio.h>
|
||||
#include <stdlib.h>
|
||||
#include <fcntl.h>
|
||||
#include <sys/mman.h>
|
||||
#include <unistd.h>
|
||||
#include <string.h>
|
||||
|
||||
#define MAP_SIZE 0x400000
|
||||
|
||||

||||

|
||||
* bar_map_base: Mapping of the BAR Base Address for the program
|
||||

This program copies the boot image to the PCIe endpoint's memory region and
|
||||
writes the necessary control words to signal image transfer completion.
