2026-01-09dm: core: Default to using DEVRES outside of xPLTom Rini
The devm alloc functions that we have may follow the Linux kernel model where allocations are (almost always) automatically free()'d. However, quite often we don't enable, in full U-Boot, the tracking and free()'ing functionality. This in turn leads to memory leaks because the driver author expects that since the functions have the same name as in the Linux Kernel they have the same behavior. In turn we then get functionally correct commits such as commit 00e1fed93c8c ("firmware: ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually add these calls. Rather than manually tracking allocations and implementing free()s, rework things so that we follow expectations by enabling the DEVRES functionality (outside of xPL phases). This turns DEVRES from a prompted symbol to a symbol that must be select'd, and we now remove our non-managed alloc/free functions from outside of xPL builds.

2025-11-20Introduce the Generic System Interconnect SubsystemNeil Armstrong
Let's introduce the Generic System Interconnect subsystem based on the counterpart Linux framework which is used to vote for bandwidth across multiple SoC busses. Documentation for the Linux Generic System Interconnect Subsystem can be found at [1]. Each bus endpoints are materialised as "nodes" which are linked together, and the DT will specify a pair of nodes to enable and set a bandwidth on the route between those endpoints. The hardware resources that provide those nodes and provides the way to vote for the bandwidth are called "providers". The Interconnect uclass code is heavily based on the Linux one, with some small differences: - nodes are allocated as udevices instead of Linux idr_alloc() - tag management is minimal, only normal xlate is supported - getting nodes states at probe is not implemented - providers are probed on demand while the nodes links are traversed - nodes are populated on bind - id management is simplified, static IDs and dynamics IDs can be used - identical consume API as Linux, only implementation differs Fully tested with associated DM test suite.

2025-06-11dm: core: use s32 instead of int for dev_read_s32_defaultQuentin Schulz
dev_read_s32_default is for getting an s32 from a Device Tree property and allows to take a default value if that property is missing. Considering it calls ofnode_read_u32_default which takes a u32 and returns a u32, it should do the same instead of using an int, especially considering that int size is typically architecture-specific, as opposed to s32/u32. s32 and u32 being the same size, dev_read_s32* functions calling ofnode_read_u32_default shouldn't be an issue (at the type level at least) as the information will be stored appropriately in 4B regardless of the sign.

2025-01-24Merge patch series "test: Improvements to ut command and test-suite running"Tom Rini
Simon Glass <sjg@chromium.org> says: The current method of running unit tests relies on subcommands of the ut command. Only the code in each subcommand knows how to find the tests related to that subcomand. This is not ideal and we now have quite a few subcommands which do nothing but locate the relevant tests in a linker list, then call a common function to run them. This series adds a list of test suites, so that these subcommands can be removed. An issue with 'ut all' is that it doesn't record how many tests failed overall, so it is necessary to examine copious amounts of output to look for failures. This series adds a new 'total' feature allow recording the total number of failed tests. To help with 'ut all' a new pytest is created which runs it (as well as 'ut info') and makes sure that all is well. Due to the 'ut all' failures this does not pass, so the test is disabled for now. It is here because it provides security against misnaming a test suite and causing it not to run. Future work may: - get 'ut all' passing - enable test_suite() in CL, to ensure that 'ut all' keeps passing - record duration of each suite - allow running the tests in random order to tease out dependencies - tweak the output to remove common prefixes - getting rid of bootstd, optee and seame 'ut' subcommands Link: https://lore.kernel.org/r/20250120212613.516664-1-sjg@chromium.org

For boards with SPL, the autoprobe is still done there as well. Note that with this change, autoprobe happens after the EVT_DM_POST_INIT_R/F events are sent, rather than before.

implementation" Christian Marangi <ansuelsmth@gmail.com> says: This series is split in 2 part. While adapting the LED boot and activity code to the new property accepted by Rob in dt-schema repository, a big BUG was discovered. The reason wasn't clear at start and took me some days to figure it out. This was triggered by adding a new phandle in the test.dts to introduce test for the new OPs. This single addition caused the sandbox CI test to fail in the dm_test_ofnode_phandle_ot test. This doesn't make sense as reverting the change made the CI test to correctly finish. Also moving the uboot node down after the first phandle (in test.dts the gpio one) also made the CI test to correctly finish. A little bit of searching and debugging made me realize the parse phandle OPs didn't support other.dts at all and they were still referencing phandle index from test.dts. (more info in the related commit) In short the test was broken all along and was working by pure luck. The first 4 patch address and fix the problem for good. The other 4 patch expand and address the property change for LED boot/activity. Posting in a single series as changes are trivial and just to speedup review process.

Implement oftree variant of parse_phandle OPs. There is currently a very hidden and laten BUG with parse_phandle OPs that doesn't permit the support of multiple DTS in a system. One usage example if sandbox with the usage of other.dts The BUG is only present on live scenario where of_... OPs are used and it's not present when fdt... OPs are used. This is caused by an assumption made in __of_parse_phandle_with_args, with the of_find_node_by_phandle call that pass the first arg as NULL. This makes of_find_node_by_phandle use the default root node of the system and doesn't permit the usage of alternative tree. This is correct for normal system and also for the linux kernel where it's assumed a single device tree. It's problematic if other device tree needs to be used. To fix this, introduce __of_root_parse_phandle_with_args to define a root device tree for of_find_node_by_phandle. Introduce all the variant OPs for this and in ofnode, the oftree OPs following how it's done for other OPs with similar task. For FDT scenario, ofnode_from_fdtdec_phandle_args is reworked to accept a new variable, node and noffset_to_ofnode is used instead of offset_to_ofnode.

2024-11-24dm: Add dm_remove_devices_active() for ordered device removalJanne Grunau
This replaces dm_remove_devices_flags() calls in all boot implementations to ensure non vital devices are consistently removed first. All boot implementation except arch/arm/lib/bootm.c currently just call dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL). This can result in crashes when dependencies between devices exists. The driver model's design document describes DM_FLAG_VITAL as "indicates that the device is 'vital' to the operation of other devices". Device removal at boot should follow this. Instead of adding dm_remove_devices_flags() with (DM_REMOVE_ACTIVE_ALL | DM_REMOVE_NON_VITAL) everywhere add dm_remove_devices_active() which does this. Fixes a NULL pointer deref in the apple dart IOMMU driver during EFI boot. The xhci-pci (driver which depends on the IOMMU to work) removes its mapping on removal. This explodes when the IOMMU device was removed first. dm_remove_devices_flags() is kept since it is used for testing of device_remove() calls in dm. Signed-off-by: Janne Grunau <j@jannau.net>

Patrick Rudolph <patrick.rudolph@9elements.com> says: Based on the existing work done by Simon Glass this series adds support for booting aarch64 devices using ACPI only. As first target QEMU SBSA support is added, which relies on ACPI only to boot an OS. As secondary target the Raspberry Pi4 was used, which is broadly available and allows easy testing of the proposed solution. The series is split into ACPI cleanups and code movements, adding Arm specific ACPI tables and finally SoC and mainboard related changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the mandatory ACPI tables are supported, allowing to boot into Linux without errors. The QEMU SBSA support is feature complete and provides the same functionality as the EDK2 implementation. The changes were tested on real hardware as well on QEMU v9.0: qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \ -pflash secure-world.rom \ -pflash unsecure-world.rom qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \ -smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \ -dtb bcm2711-rpi-4-b.dtb -nographic Tested against FWTS V24.03.00.

2024-10-17usb: tcpm: add core frameworkSebastian Reichel
This adds TCPM framework in preparation for fusb302 support, which can handle USB power delivery messages. This is needed to solve issues with devices, that are running from a USB-C port supporting USB-PD, but not having a battery. Such a device currently boots to the kernel without interacting with the power-supply at all. If there are no USB-PD message replies within 5 seconds, the power-supply assumes the peripheral is not capable of USB-PD. It usually takes more than 5 seconds for the system to reach the kernel and probe the I2C based fusb302 chip driver. Thus the system always runs into this state. The power-supply's solution to fix this error state is a hard reset, which involves removing the power from VBUS. Boards without a battery (or huge capacitors) will reset at this point resulting in a boot loop. This imports the TCPM framework from the kernel. The porting has originally been done by Rockchip using hardware timers and the Linux kernel's TCPM code from some years ago. I had a look at upgrading to the latest TCPM kernel code, but that beast became a lot more complex due to adding more USB-C features. I believe these features are not needed in U-Boot and with multiple kthreads and hrtimers being involved it is non-trivial to port them. Instead I worked on stripping down features from the Rockchip port to an even more basic level. Also the TCPM code has been reworked to avoid complete use of any timers (Rockchip used SoC specific hardware timers + IRQ to implement delayed work mechanism). Instead the delayed state changes are handled directly from the poll loop. Note, that (in contrast to the original Rockchip port) the state machine has the same hard reset quirk, that the kernel has - i.e. it avoids disabling the CC pin resistors for devices that are not self-powered. Without that quirk, the Radxa Rock 5B will not just end up doing a machine reset when a hard reset is triggered, but will not even recover, because the CPU will loose power and the FUSB302 will keep this state because of leak voltage arriving through the RX serial pin (assuming a serial adapter is connected). This also includes a 'tcpm' command, which can be used to get information about the current state and the negotiated voltage and current.

2023-10-15drivers: introduce Secure Monitor uclassAlexey Romanov
At the moment, we don't have a common API for working with SM, only the smc_call() function. This approach is not generic and difficult to configure and maintain. This patch adds UCLASS_SM with the generic API: - sm_call() - sm_call_write() - sm_call_read() These functions operate with struct pt_regs, which describes Secure Monitor arguments.

2023-10-13firmware: scmi: implement SCMI base protocolAKASHI Takahiro
SCMI base protocol is mandatory according to the SCMI specification. With this patch, SCMI base protocol can be accessed via SCMI transport layers. All the commands, except SCMI_BASE_NOTIFY_ERRORS, are supported. This is because U-Boot doesn't support interrupts and the current transport layers are not able to handle asynchronous messages properly.
