2026-06-29treewide: Staticize and constify acpi opsMarek Vasut
Set the acpi_ops structure as static const where applicable. The The structure is not accessible from outside of drivers and is not going to be modified at runtime. The structure may be unused in a couple of drivers depending on their configuration, mark those sites with __maybe_unused .

2026-05-25cros_ec: Sync ec_commands.h from upstream Chrome OS ECSimon Glass
Sync include/ec_commands.h from upstream commit 4f3d17aa34 ("skywalker: set SLEEP_TIMEOUT_MS to 50 seconds"). The new file makes two build assumptions that do not hold for U-Boot. It hides '<stdint.h>' from __KERNEL__ builds, leaving UINT16_MAX (used by EC_RES_MAX) undefined for U-Boot; widen the gate to '!defined(__KERNEL__) || defined(__UBOOT__)' It gates '<linux/limits.h>' on '#ifdef __KERNEL__'; the matching '#else' branch defines BIT()/BIT_ULL()/GENMASK()/GENMASK_ULL() locally, assuming kernel headers provide those macros otherwise. U-Boot defines __KERNEL__ too but has no <linux/limits.h>. Nest a '!defined(__UBOOT__)' check around the include so the __UBOOT__ path stays in the __KERNEL__ branch (no local BIT/GENMASK defines), which avoids redefinition warnings against U-Boot's linux/bitops.h. Pull in linux/bitops.h up front for U-Boot so the file's own BIT() and GENMASK() uses still resolve. Adapt callers to two interface changes. The 'ec_current_image' enum tag is now 'ec_image' (EC_IMAGE_* constants unchanged); rename it in affected files to match. The VBNV-context interface was dropped upstream, but it still used in lab Chromebooks; keep those constants and structs in cros_ec.h Likewise, MEC_EMI_BASE and MEC_EMI_SIZE are a U-Boot-local addition to ec_commands.h that the upstream sync removes; preserve them in cros_ec.h next to the VBNV block, and switch the only consumer (arch/x86/cpu/apollolake/cpu_spl.c) to include cros_ec.h Signed-off-by: Simon Glass <[email protected]>

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.

2021-01-05x86: apl: Adjust how the UART gets its platform dataSimon Glass
