Learning: For the Armbian build project, maintaining consistency with existing patches across U-Boot versions (such as between 2025.01 and 2025.04) is prioritized over refactoring individual patches for code improvements.

Learning: When reviewing kernel or u-boot version bump PRs in the Armbian build system, check if patches existed in previous kernel version directories (e.g., sunxi-6.12, sunxi-6.13) before describing them as new features. If a patch and the majority of its contents existed previously with no major functionality changes, focus the review on the actual changes: the version bump itself and patch compatibility adjustments. Don't describe existing patches being ported/maintained across versions as new features or drivers—this is misleading. The patches are existing code being re-aligned to work with the new upstream version.

Learning: For the Armbian genio family (config/sources/families/genio.conf and patch/u-boot/u-boot-genio/), when reviewing PRs that include vendor U-Boot patches from Collabora, avoid flagging potential issues in board configurations that are out of scope for the PR's primary focus (e.g., don't flag Genio 510/700 board issues when the PR is focused on radxa-nio-12l/Genio 1200). The maintainer prioritizes keeping vendor patches close to upstream for easier re-copying and maintenance, even if secondary board configs have potential mismatches.

Learning: In the Armbian build system for SpacemiT U-Boot patches (patch/u-boot/legacy/u-boot-spacemit-k1/), alignment with mainline U-Boot behavior is prioritized. For example, in boot mode handling, leaving devnum unchanged in the default case (when devtype is cleared) follows mainline conventions rather than explicitly clearing it to handle edge cases.

Learning: In the Armbian build system, the write_uboot_platform() function implementations follow different patterns across Rockchip family files. The newer standard (used in rockchip64_common.inc and rk3506) includes 'status=none' parameter in dd commands, while older implementations (rk3288, rk322x) use an older pattern without this parameter. The rk3506 implementation correctly follows the current Rockchip family standard.

The current and edge branches for uefi-x86 are specifically configured for Apple T2-based x86 machines, including T2-specific patches from the linux-t2 project and custom kernel configuration options for Apple hardware drivers.

Timestamp: 2025-11-20T18:20:11.985Z
Learning: The rewrite-patches tool (REWRITE_PATCHES=yes) in the Armbian build system can inadvertently introduce semantic changes when the u-boot/kernel git base revision differs from expected state. The tool applies patches, commits them, and re-exports them using git format-patch, which can cause the re-exported patch to reflect the base revision's state rather than preserving the original patch intent. This is particularly problematic for device tree changes like interrupt specifications. The tool currently lacks validation mechanisms to detect such semantic drift, and affected patches must be manually corrected after rewriting.

Learning: In the Armbian build system, for recurring maintenance tasks like kernel version bumping, TODO comments should use generic version formats (e.g., "MAJOR.MINOR-rc1") rather than specific version numbers (e.g., "6.17-rc1") to avoid the need for frequent comment updates that would create unnecessary maintenance overhead.

The "current" and "edge" naming is reserved for mainline kernel branches.

The rk35xx family configuration sources rockchip64_common.inc, which provides edge and current kernel branch definitions, making these branches available even though they're not defined directly in rk35xx.conf.

The gating mechanism in pre_config_uboot_target__build_first_stage function works as intended to conditionally build/copy tiboot3.bin only when TIBOOT3_BOOTCONFIG is defined.

Learning: In the Armbian build system, vendor branch configurations in family files are designed to be shared across multiple SoCs within the same family that use the same vendor kernel tree. For example, rk35xx and rockchip-rk3588 families both use identical vendor branch settings (same KERNELSOURCE, KERNELBRANCH, and KERNELPATCHDIR), demonstrating that vendor branches are intentionally generic rather than SoC-specific.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

Learning: In Armbian build configs for vendor kernel sources, prefer the following branch naming conventions: use 'vendor' or 'vendor-rt' for stable vendor releases, and 'vendor-edge' for bleeding-edge/pre-release vendor versions. The 'edge' naming without the 'vendor-' prefix is reserved for mainline kernel branches. Apply this pattern to family config files under config/sources/families (e.g., spacemit.conf) to ensure consistent vendor kernel sourcing naming across the repository.

15-15: Version bump to final release is correct.

The change from release candidate (v2026.01-rc5) to final release (v2026.01) follows the expected progression. The tag exists in the upstream U-Boot repository as of January 5, 2026.
