2026-02-17treewide: Clean up DECLARE_GLOBAL_DATA_PTR usagePeng Fan
Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

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.

Provide armffa command showcasing the use of the U-Boot FF-A support armffa is a command showcasing how to invoke FF-A operations. This provides a guidance to the client developers on how to call the FF-A bus interfaces. The command also allows to gather secure partitions information and ping these partitions. The command is also helpful in testing the communication with secure partitions. For more details please refer to the command documentation [1]. A Sandbox test is provided for the armffa command.

2023-08-08arm_ffa: introduce Arm FF-A supportAbdellatif El Khlifi
Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0 The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1] describes interfaces (ABIs) that standardize communication between the Secure World and Normal World leveraging TrustZone technology. This driver uses 64-bit registers as per SMCCCv1.2 spec and comes on top of the SMCCC layer. The driver provides the FF-A ABIs needed for querying the FF-A framework from the secure world. The driver uses SMC32 calling convention which means using the first 32-bit data of the Xn registers. All supported ABIs come with their 32-bit version except FFA_RXTX_MAP which has 64-bit version supported. Both 32-bit and 64-bit direct messaging are supported which allows both 32-bit and 64-bit clients to use the FF-A bus. FF-A is a discoverable bus and similar to architecture features. FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed by the PSCI driver. Clients are able to probe then use the FF-A bus by calling the DM class searching APIs (e.g: uclass_first_device). The Secure World is considered as one entity to communicate with using the FF-A bus. FF-A communication is handled by one device and one instance (the bus). This FF-A driver takes care of all the interactions between Normal world and Secure World. The driver exports its operations to be used by upper layers. Exported operations: - ffa_partition_info_get - ffa_sync_send_receive - ffa_rxtx_unmap Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c). Arm specific methods are implemented in the Arm driver (arm-ffa.c). For more details please refer to the driver documentation [2].
