doc: board: ti: fix incorrect labels for boot switches

2026-03-27T09:56:01Z

The labels for the boot mode switches were incorreclty documented for some TI boards, this patch fixes them as per the official user guides linked below: AM62x https://www.ti.com/lit/ug/spruj40e/spruj40e.pdf AM62dx https://www.ti.com/lit/ug/sprujg2/sprujg2.pdf AM62ax https://www.ti.com/lit/ug/spruj66b/spruj66b.pdf AM62px https://www.ti.com/lit/ug/spruj40e/spruj40e.pdf AM6254atl https://www.ti.com/lit/ug/spruja1a/spruja1a.pdf Signed-off-by: Anshul Dalal

doc: board: fix OPTEE args for TI SoCs

2026-03-27T09:55:46Z

CFG_WITH_SOFTWARE_PRNG=y was added as an OPTEE argument to workaround some bugs related to TRNG which have been fixed now[1]. Therefore this patch drops the redundant argument from the documentation.

treewide: fix uImage.FIT document paths

2026-03-27T09:50:29Z

Commit 488445cefa1 ("doc: Move FIT into its own directory") moved the documentation in doc/uImage.FIT to doc/usage/fit, subsequently all documents and example sources have been converted to reStructuredText. Fix (almost) all of the remaining occurrences of the old path and filenames across the tree. The exception is doc/uImage.FIT/command_syntax_extensions.txt which apparently has been removed entirely, or at least I was unable to locate where that document is now. Signed-off-by: Daniel Golle

doc: board: samsung: exynos-mobile: remove requirement of stub device tree

2026-02-23T06:35:33Z

Flashing U-Boot for Exynos 7870 requires creating a stub device tree, where certain properties and nodes are defined which are populated by the previous bootloader in the phones. Since these properties are now available in the U-Boot device tree, it's now possible to use the same blob generated by U-Boot in place of the stub, when creating boot images. Update the build documentation to reflect the same. Signed-off-by: Kaustabh Chakraborty Signed-off-by: Minkyu Kang

doc: board: samsung: exynos-mobile: use u-boot-nodtb.bin for packaging process

2026-02-23T06:35:33Z

U-Boot for this board is programmed to use the external DTB if an internal device tree is not available. This makes it safe to build boot images using the non-DTB U-Boot binary, while taking up less space. Reflect this change in documentation.

doc: board: samsung: exynos-mobile: add DEVICE_TREE make flag in build

2026-02-23T06:35:33Z

Since there is only one internal device tree allowed in U-Boot, the DEVICE_TREE flag is required for building images for various devices. Document it in the build guide. Signed-off-by: Kaustabh Chakraborty Signed-off-by: Minkyu Kang

Merge patch series "m68k: Add support for QEMU virt machine"

2026-02-02T20:25:48Z

Kuan-Wei Chiu says: Add support for the QEMU 'virt' machine on the m68k architecture. The QEMU virt machine models a generic system utilizing Goldfish virtual peripherals and is capable of emulating various classic 68k CPUs. Currently, U-Boot's m68k architecture support focuses on ColdFire variants. This series expands support to include the classic M680x0 architecture, implementing the necessary exception vectors, startup code, and a bootinfo parser compatible with the QEMU interface. Drivers for Goldfish peripherals (TTY, Timer, RTC) and the QEMU Virtual System Controller (sysreset) are also added to enable serial console, timekeeping, and system reset functionality. The implementation has been verified on QEMU targeting the M68040 CPU, confirming successful hardware initialization and boot to the U-Boot command shell. Additionally, the CI configuration was verified locally using gitlab-ci-local "qemu_m68k_virt test.py", resulting in PASS qemu_m68k_virt test.py.

board: Add QEMU m68k virt board support

2026-02-02T20:24:41Z

Add support for the QEMU 'virt' machine on the m68k architecture. This board emulates a generic machine based on the Motorola 68040 CPU equipped with Goldfish virtual peripherals. Introduce the necessary board configuration and initialization infrastructure. The implementation includes logic to parse the QEMU bootinfo interface, enabling dynamic detection of system RAM size to adapt to the virtual machine's configuration. Enable the Goldfish TTY driver for serial console output. Additionally, enable Goldfish RTC and timer drivers to support real-time clock functionality and nanosecond-resolution delays. Include comprehensive documentation covering build instructions and usage examples. Signed-off-by: Kuan-Wei Chiu Tested-by: Daniel Palmer Reviewed-by: Simon Glass
