4 daysfit: Rework SPL_LOAD_FIT_ADDRESS slightlyTom Rini
Options which deal with memory locations and have a default value of 0x0 are dangerous, as that is often not a valid memory location. Rework SPL_LOAD_FIT_ADDRESS as follows: - Add SPL_HAS_LOAD_FIT_ADDRESS to guard prompting the question as the case of loading a FIT image does not strictly require setting an address and allows for a malloc()'d area to be used. - For SPL_RAM_SUPPORT, select the new guard symbol if SPL_LOAD_FIT is enabled because in that case an address must be provided. - Update defconfigs for these new changes. Largely this means some defconfigs need to enable SPL_HAS_LOAD_FIT_ADDRESS to maintain their current status. In the case of sandbox, we also need to set SPL_LOAD_FIT_ADDRESS to 0x0.

2026-01-16spl: fix incorrect dependency for SPL_NETQuentin Schulz
When SPL_NET is included, scripts/Makefile.xpl includes net/. However, in this directory, the Makefile only compiles things if CONFIG_NET or CONFIG_NET_LWIP is defined (it doesn't use $(PHASE_)). Therefore, at least one networking stack needs to be enabled for SPL_NET=y to do anything meaningful. In certain cases (e.g. am62px_evm_r5_ethboot_defconfig + NO_NET=y via menuconfig), it is possible to fail the build with undefined references (since include/net-common.h does check with CONFIG_IS_ENABLED(NET) which would be true for SPL_NET, but the implementation wouldn't be compiled). Fix this oversight by making sure a network stack (and the legacy one) is available when selecting SPL_NET.

2025-11-06common/spl: fix endless loop in spl_fit_append_fdt()Michael Walle
Technically, commit 24bf44cf88e7 ("spl: fit: Do not fail immediately if an overlay is not available") introduced that regression as the code will never advance if spl_fit_get_image_name() will return an error. But at that time, spl_fit_get_image_node() was used in spl_fit_append_fdt() which calls fdt_subnode_offset() to get the image node. And I presume the commit was about the latter failing gracefully and trying the next one. But with commit b13eaf3bb4e6 ("spl: fit: Add board level function to decide application of DTO") that behavior changed and the loop in spl_fit_append_fdt() no longer uses spl_fit_get_image_node() but spl_fit_get_image_name() directly. Thus it doesn't make any sense to not break the loop if that fails. Also, the original use case of commit 24bf44cf88e7 ("spl: fit: Do not fail immediately if an overlay is not available") is preserved because spl_subnode_offset() is now called within the loop and errors are handled gracefully (and advancing the index).

2025-11-06spl: Add support for Device Firmware Upgrade (DFU) over PCIeHrushikesh Salunke
Introduces support for Device Firmware Upgrade (DFU) over PCIe in U-Boot. Traditionally, the DFU protocol is used over USB, where a device enters DFU mode and allows a host to upload firmware or binary images directly via the USB interface. This is a widely adopted and convenient method for updating firmware. In the context of Texas Instruments (TI) SoCs, PCIe can be used as a boot interface in a manner that differs from the conventional "PCIe Boot" process, which typically refers to booting an OS or firmware image from an NVMe SSD or other PCIe-attached storage devices. Instead, TI SoCs can be configured as a PCIe Endpoint, allowing a connected PCIe Root Complex (host) to transfer images directly into the device’s memory over the PCIe bus for boot purposes. This mechanism is analogous to DFU over USB, but leverages the high-speed PCIe link and does not depend on traditional storage devices. By extending the DFU framework in U-Boot to support PCIe, it will be possible to flash images over PCIe. While this implementation is motivated by TI SoC use cases, the framework is generic and can be adopted by everyone for platforms that support PCIe Endpoint mode. Platforms with hardware support for PCIe-based memory loading can use this to implement PCIe as a boot mode, as well as to enable flashing and recovery scenarios similar to DFU over USB. In summary, enable support for: - DFU-style flashing of firmware/images over PCIe, analogous to existing USB DFU workflows - PCIe as a boot mode where a host can load images directly into device memory using DFU over PCIe Signed-off-by: Hrushikesh Salunke <h-salunke@ti.com> Reviewed-by: Mattijs Korpershoek <mkorpershoek@kernel.org> Link: https://lore.kernel.org/r/20251023080922.3527052-1-h-salunke@ti.com Signed-off-by: Mattijs Korpershoek <mkorpershoek@kernel.org>

On platforms with non-secure falcon mode, SPL_BOOTZ is enabled by default for 32-bit ARM systems and SPL_BOOTI is enabled by default for 64-bit ARM and RISCV. The respective C files (image.c/zimage.c) are compiled based on library symbols $(PHASE_)LIB_BOOTx instead which are in turn selected by both CMD_BOOTx and SPL_BOOTx as required.

2025-10-22spl: split spl_board_fixups to arch/board specificAnshul Dalal
The current spl_board_fixups API allows for modification of spl_image before the SPL jumps to it. This can be used to modify the DT for the next boot stage, however the current API only allows either the machine arch or the board to use it. This limits the utility of the API as there might be certain fixups that should be applied to all boards sharing the same machine architecture with others being board specific. For TI's K3 specifically, this prevents us from performing architecture level fixups since a lot of TI boards are already making use of the spl_board_fixups API. Therefore this patch splits the API into two to allow both board and the architecture specific fixups. The order is kept as arch then board to give board specific fixups the precedence.

2025-10-07Merge patch series "Add support for secure falcon mode: load kernel image ↵Tom Rini
before args" Anshul Dalal <anshuld@ti.com> says: During the implementation of falcon mode for TI's K3 devices [1], I encountered several limitations in regards to the current falcon mode support in U-Boot especially in ensuring a secure boot flow. Although the current implementation allows for loading of a signed fitImage as the SPL payload, there are still a few edge cases that might allow bypassing the verified boot path. The following issues with current falcon mode need to be resolved: 1) No fallback: We currently fallback to regular boot flow if falcon mode fails, this might not be secure. 2) No arguments file: We currently load a kernel file (which could be a raw image or FIT) alongside an args file (usually the DT). The args file here doesn't have any verification mechanism, so should be skipped altogether as the FIT can contain the DT. 3) No access to env: In ext and fat fs boot, currently we also reads the environment to get the names of the kernel and the arg file. This should be disabled in secure falcon flow as the env might not be secure. 4) No raw image boot: Boot should fail when the kernel file is a raw kernel image, only FIT should be allowed. As per the recommendation of maintainers[2], I have decided to split the above set of tasks into multiple patch series. This is the first one which fixes the load order of kernel image and the args file in falcon mode. Along with some minor cleanup.

Currently in falcon mode, the FS and raw mmc boot loads the args file first followed by the kernel image whereas others load in the opposite order. This inconsistency means falcon boot doesn't behave the same across various boot media. For example, in the case where the kernel file is a FIT with the kernel image present alongside the dtb and the args file is another DT, which DT should be picked? The one form the FIT or the one set by the args file? Currently this depends entirely on how the boot media handles falcon mode. Therefore, this patch enforces the load order of the kernel image first followed by the args file in FAT FS boot. So in the above example, the args file would take precedence.
