mips: mtmips: add CPU reset support for MT7628

2026-02-03T18:51:37Z

Allow the system to reset the CPU without calling the reset controller. This patch also removed the default SYSRESET controller for MT7628, as it is now optional. Signed-off-by: Shiji Yang

mips: Update linker scripts to ensure appended device tree is aligned

2026-01-20T18:07:16Z

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: - Aligns the final section before _end (for U-Boot) or _image_binary_end (for xPL phases) by 8-bytes by adding '. = ALIGN(8);' to the final section before the symbol. For SPL we need this in two places to cover all build configurations. - Remove now-spurious '. = ALIGN(x);' statements that were intended to provide the above alignments. - Ensure that we do have alignment by adding an ASSERT so that when not aligned we fail to link (and explain why).

kbuild: Bump the build system to 6.1

2026-01-02T16:28:14Z

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.

MIPS: Assure end of U-Boot is at 8-byte aligned offset

2025-11-28T16:20:22Z

Make sure the end of U-Boot is at 8-byte aligned offset, not 4-byte aligned offset. This allows safely appending DT at the end of U-Boot with the guarantee that the DT will be at 8-byte aligned offset. This 8-byte alignment is now checked by newer libfdt 1.7.2 . Signed-off-by: Marek Vasut

global: Make ARCH_MISC_INIT a selected symbol

2025-07-11T17:33:25Z

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. Acked-by: Peng Fan Signed-off-by: Tom Rini

Merge patch series "list.h/treewide: get rid of no-op prefetch()"

2025-06-18T14:05:29Z

Rasmus Villemoes says: While looking through list.h, I saw that the regular list_* helpers (and one of the hlist_* ones) still contain the prefetch() that was removed in linux 14 years ago. It doesn't do anything, but makes the macros harder to read, so get rid of it, and the fallback, no-op definition that they relied on. That requires removing a few uses outside list.h as well. checkpatch warns about some whitespace issues in list.h, but as I've copied whole kerneldoc+#define blocks directly from the linux kernel, I think it's better to just accept that so that we don't introduce needless diffs. The "macro argument reuse" arguments should also be ignored, as e.g. the "member" arguments are obviously always just bare identifiers, and the "pos" arguments must be assigned to multiple times.

mips: drop unused prefetch code and logic

AFAICT, CONFIG_CPU_HAS_PREFETCH has never existed as a proper Kconfig symbol in U-Boot, nor has any board include file ever defined it. Signed-off-by: Rasmus Villemoes

Merge patch series "Hex value prefix case cleanup"

2025-06-14T15:10:48Z

E Shattow says: Make consistent use of lowercase hexadecimal prefix '0x' throughout U-Boot. There are a few remaining uses of uppercase 'X' to denote hexadecimal prefix or placeholder in documentation and error messages. External devicetree-rebasing dts/upstream and the generated code of xilinx/zynq are ignored for the series. Link: https://lore.kernel.org/r/20250606224558.1117422-1-e@freeshell.de
