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.

2026-01-20arm: Update linker scripts to ensure appended device tree is alignedTom Rini
With commit 0535e46d55d7 ("scripts/dtc: Update to upstream version v1.7.2-35-g52f07dcca47c") it is now a fatal error to U-Boot if our device tree is not 8-byte aligned. In commit 85f586035d75 ("ARM: OMAP2+: Pad SPL binary to 8-byte alignment before DTB") Beleswar Padhi explains that we must have ALIGN(x) statements inside of a section to ensure that padding is included and not simply that the linker address counter is incremented. To that end, this patch: - Expands some linker sections to be more readable when adding a second statement to the section. - Aligns the final section before _end (for U-Boot) or _image_binary_end or __bss_end (for xPL phases) by 8-bytes by adding '. = ALIGN(8);' to the final section before the symbol. - Ensure that we do have alignment by adding an ASSERT so that when not aligned we fail to link (and explain why). - Remove now-spurious '. = ALIGN(x);' statements that were intended to provide the above alignments.

2026-01-02kbuild: Bump the build system to 6.1Sughosh Ganu
Our last sync with the kernel was 5.1. We are so out of sync now, that tracking the patches and backporting them one by one makes little sense and it's going to take ages. This is an attempt to sync up Makefiles to 6.1. Unfortunately due to sheer amount of patches this is not easy to review, but that's what we decided during a community call for the bump to 5.1, so we are following the same guidelines here.

2025-07-11global: Make ARCH_MISC_INIT a selected symbolTom Rini
This symbol is not something that the user should be enabling or disabling but rather the developer for a particular board should select it when required. This is mostly size neutral, however a few places do have changes. In the case of i.MX6ULL systems, it is always the case that arch_misc_init() could call setup_serial_number() and do useful work, but was not enabled widely, but now is. In the case of i.MX23/28 systems, we should be able to call mx28_fixup_vt() again here, so do so. Finally, some platforms were calling arch_misc_init() and then not doing anything and this results in removing the option.

2023-10-22sunxi: psci: stop modeling register layout with C structsSam Edwards
Since the sunxi support nowadays generally prefers #defined register offsets instead of modeling register layouts using C structs, now is a good time to do this for PSCI as well. This patch moves away from using the structs `sunxi_cpucfg_reg` and `sunxi_prcm_reg` in psci.c. The former struct and its associated header file existed only to support PSCI code, so also delete them altogether.

2023-10-22sunxi: refactor serial base addresses to avoid asm/arch/cpu.hAndre Przywara
At the moment we have each SoC's memory map defined in its own cpu.h, which is included in include/configs/sunxi_common.h. This will be a problem with the introduction of Allwinner RISC-V support. Remove the inclusion of that header file from the common config header, instead move the required serial base addresses (for the SPL) into a separate header file. Then include the original cpu.h file only where we really need it, which is only under arch/arm now. This disentangles the architecture specific header files from the generic code.

2023-10-11ARM: psci: move GIC address override to KconfigAndre Przywara
As the code to switch an ARM core from secure to the non-secure state needs to know the base address of the Generic Interrupt Controller (GIC), we read an Arm Cortex defined system register that is supposed to hold that base address. However there are SoCs out there that get this wrong, and this CBAR register either reads as 0 or points to the wrong address. To accommodate those systems, so far we use a macro defined in some platform specific header files, for affected boards. To simplify future extensions, replace that macro with a Kconfig variable that holds this override address, and define a default value for SoCs that need it.

It is not a parse error to have a default value of "0" for a "hex" type entry, instead of "0x0". However, "0" and "0x0" are not treated the same even by the tools themselves. Correct this by changing the default value from "0" to "0x0" for all hex type questions that had the incorrect default. Fix one instance (in two configs) of a default of "0" being used on a hex question to be "0x0". Remove the cases where a defconfig had set a value of "0x0" to be used as the default had been "0".

Rename current assembler implementation of allow_unaligned() to v7_arch_cp15_allow_unaligned() and add it into armv7.h header, then add C wrapper of allow_unaligned(). This fixes misbehavior when linking U-Boot on ARMv7a i.MX6Q, where the CPU specific allow_unaligned() implementation was ignored and instead the __weak allow_unaligned() implementation from lib/efi_loader/efi_setup.c was used, which led to "data abort" just before booting Linux via tftp, in efi_dp_from_file() -> path_to_uefi() -> utf16_put() . The problem is triggerd by c7c0ca37673 ("efi_loader: fix efi_dp_from_file()") . Adding the wrapper fixes the problem.
