OPTEE-OS on ARMv7a" This series from Marek Vasut <[email protected]> brings some enhancements to use cases using OPTEE-OS on ARMv7a platforms, some of which already existed on ARMv8. Link: https://lore.kernel.org/r/[email protected]
2025-11-06ARM: bootm: Add support for starting Linux through OPTEE-OS on ARMv7aMarek Vasut
Add support for jumping to Linux kernel through OPTEE-OS on ARMv7a. This is only supported if U-Boot runs in PL1 secure. This change adds two components, one is fitImage OPTEE-OS loadable handler, which makes a note of OPTEE-OS being loaded and stores the load address for later jump to it. The second part is the actual jump to Linux through OPTEE-OS. The jump through OPTEE-OS requires set up of multiple CPU registers, r1 and r2 are passed through, r0 and r3 have to be set to 0, lr is set to Linux kernel entry point. This setup is done by new assembler function boot_jump_linux_via_optee(). The boot_jump_linux_via_optee() also includes STM32MP13xx late TZC configuration write, this cannot be moved easily, hence the ifdef. Signed-off-by: Marek Vasut <[email protected]>
2025-11-03spl: remove usage of CMD_BOOTx from image parsingAnshul Dalal
Using CMD_* configs from spl doesn't make logical sense. Therefore this patch replaces the checks for CMD_BOOTx with newly added library symbols LIB_BOOT[IMZ] and SPL_LIB_BOOT[IMZ] which are enabled by their respective CMD_* or SPL_* counterparts. 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.

2025-04-11Merge patch series "Switch to using $(PHASE_) in Makefiles"Tom Rini
Tom Rini <[email protected]> says: This series switches to always using $(PHASE_) in Makefiles when building rather than $(PHASE_) or $(XPL_). It also starts on documenting this part of the build, but as a follow-up we need to rename doc/develop/spl.rst and expand on explaining things a bit. Link: https://lore.kernel.org/r/[email protected]
2025-04-11Kbuild: Always use $(PHASE_)Tom Rini
It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in.

2024-10-27Merge patch series "Implement ACPI on aarch64"Tom Rini
Patrick Rudolph <[email protected]> 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. Known issues: - The QEMU rpi4 support is currently limited as it doesn't emulate PCI, USB or ethernet devices! - The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly cache related). - PCI on RPI4 isn't working on real hardware since the pcie_brcmstb Linux kernel module doesn't support ACPI yet.

2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <[email protected]> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.

2023-08-17arm: Use builtins for ffs/flsSean Anderson
Since ARMv5, the clz instruction allows for efficient implementation of ffs/fls with builtins. Until ARMv7 (with Thumb-2), this instruction is only available in ARM mode. LTO makes it difficult to force specific functions to be in ARM mode, as it is effectively a form of very aggressive inlining. To work around this, fls/ffs are implemented in assembly for ARMv5 and ARMv6 when compiling U-Boot in Thumb mode. Overall, this saves around 75 bytes per call. This code is synced with v5.15 of the Linux kernel. Signed-off-by: Sean Anderson <[email protected]> Reviewed-by: Tom Rini <[email protected]>

Before this commit, the SPL could enable the PL310 L2 cache [1], but the cache maintenance functions from cache-pl310.c were only useable for non-SPL builds. After enabling the cache one must be able to flush it, too. Thus this commit allows cache-pl310.c to be included in the SPL build.

2022-04-04arm: init: save previous bootloader dataDzmitry Sankouski
When u-boot is used as a chain-loaded bootloader (replacing OS kernel), previous bootloader leaves data in RAM, that can be reused. For example, on recent arm linux system, when chainloading u-boot, there are initramfs and fdt in RAM prepared for OS booting. Initramfs may be modified to store u-boot's payload, thus providing the ability to use chainloaded u-boot to boot OS without any storage support. Two config options added: - SAVE_PREV_BL_INITRAMFS_START_ADDR saves initramfs start address to 'prevbl_initrd_start_addr' environment variable - SAVE_PREV_BL_FDT_ADDR saves fdt address to 'prevbl_fdt_addr' environment variable Signed-off-by: Dzmitry Sankouski <[email protected]> Cc: Tom Rini <[email protected]>
2022-04-01spl: Add semihosting boot methodSean Anderson
This adds a boot method for loading the next stage from the host. It is mostly modeled off of spl_load_image_ext. I am not really sure why/how spl_load_image_fat uses three different methods to load the image, but the simple case seems to work OK for now. To control the presence of this boot method, we add a config symbol. While we're at it, we update the original semihosting config symbol. I think semihosting has some advantages of other forms of JTAG boot. Common other ways to boot from JTAG include: - Implementing DDR initialization through JTAG (typically with dozens of lines of TCL) and then loading U-Boot. The DDR initialization typically uses hard-coded register writes, and is not easily adapted to different boards. BOOT_DEVICE_SMH allows booting with SPL, leveraging U-Boot's existing DDR initialization code. This is the method used by NXP's CodeWarrior IDE on Layerscape processors (see AN12270). - Loading a bootloader into SDRAM, waiting for it to initialize DDR, and then loading U-Boot. This is tricky, because the debugger must stop the boot after the bootloader has completed its work. Trying to load U-Boot too early can cause failure to boot. This is the method used by Xilinx with its Zynq(MP) processors. - Loading SPL with BOOT_DEVICE_RAM and breaking before SPL loads the image to load U-Boot at the appropriate place. This can be a bit tricky, because the load address is dependent on the header size. An elf with symbols must also be used in order to stop at the appropriate point. BOOT_DEVICE_SMH can be viewed as an extension of this process, where SPL automatically stops and tells the host where to place the image. Signed-off-by: Sean Anderson <[email protected]>
2021-09-24arm64: arch/arm/lib: Add optimized memset/memcpy/memmove functionsStefan Roese
Ported from https://github.com/ARM-software/optimized-routines These files are included from this repository, including the latest git commit ID: string/aarch64/memcpy.S: afd6244a1f8d string/aarch64/memset.S: e823e3abf5f8 string/asmdefs.h: e823e3abf5f8 Note that memmove is also handled by the memcpy function. Please note that when adding these optimized functions as default memset memcpy functions in U-Boot, U-Boot fails to boot on the LX2160ARDB. After the initial ATF output, no U-Boot output is shown on the serial console. Some exception is triggered here in the very early boot process as some of the assembler opcodes need the caches to be enabled. Because of this, a follow-up patch will add a check to use a simple non-optimized memset for the "cache disabled" case. Note: I also integrated and tested with the Linux versions of these optimized functions. They are similar to the ones now integrated but these ARM versions are still a small bit faster.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <[email protected]>

2016-08-05ARM: Rework and correct barrier definitionsTom Rini
As part of testing booting Linux kernels on Rockchip devices, it was discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for some cases incomplete isb definitions. This was causing a failure to boot of the Linux kernel. In order to solve this problem as well as cover any corner cases that we may also have had a number of changes are made in order to consolidate things. First, <asm/barriers.h> now becomes the source of isb/dsb/dmb definitions. This however introduces another complexity. Due to needing to build SPL for 32bit tegra with -march=armv4 we need to borrow the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete form. Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add a comment about it. Now that we can always know what the target CPU is capable off we can get always do the correct thing for the barrier.
