u-boot.mk: support Python 3.12 and 3.13

2025-07-01T17:07:46Z

Fixes the following build problem on systems with Python 3.12 or 3.13: Checking 'python3-setuptools'... failed. Checking 'swig'... ok. u-boot: Please install the Python3 setuptools module Signed-off-by: Stijn Tintel

uboot-mk: Enable specifying defconfig fragments

2025-06-07T19:10:28Z

U-Boot allows specifying additional KConfig fragments to be applied on top of a defconfig. These are usually located in the board sub-directory. make foo_defconfig bar.config baz.config Add support for specifying additional KConfig fragments using the UBOOT_CONFIG variable. Treat the first word in UBOOT_CONFIG as the name of the defconfig, any additional words as additional fragments. This can be useful to distinguish between different variants of U-Boot builds such as different RAM, storage (NAND/eMMC), security etc. While c05c0699d479 (u-boot.mk: add support for config customization, 2023-06-02) already added means to modify specific KConfig options directly from the OpenWrt Makefile, leveraging existing fragments the U-Boot source-dir provides a more convenient way to extend the config when customising more than just one or two options. Furthermore it is desirable to leverage existing fragments from upstream U-Boot where they exist.

uboot-bcm4908: fix build with GCC14

2025-05-22T22:10:23Z

A lot of warnings were treated as errors after the default compiler switched to GCC14. It's hard to fix them one by one, and this u-boot is not maintained by upstream, so let's just silence these warnings.

u-boot.mk: pass CROSS_COMPILE during config

u-boot.mk: override default PATH to avoid pick hostpkg python

2024-03-02T13:17:31Z

hostpkg python from packages feed can be picked when do a incremental build because hostpkg has higher priority in PATH. It may lead build faliure as it's heavily trimmed (e.g. lacks necessary modules). For uboot which uses binman and intree dtc, this is forced as hostpkg python will never provide those modules by default. Signed-off-by: Tianling Shen

u-boot: introduce dependencies check for swig and pyelftools

2023-11-26T18:44:56Z

They are required by modern u-boot builds, e.g. uboot-rockchip and uboot-sunxi. Signed-off-by: Tianling Shen

u-boot.mk: do not force parallel build

2023-11-19T16:18:30Z

Some patched u-boots may have problems with parallel build. Do not enforce parallel build here so one can set PKG_BUILD_PARALLEL:=0 in the specific u-boot Makefile also before including the u-boot.mk. Signed-off-by: Martin Schiller

u-boot.mk: add support for config customization

2023-06-10T19:31:07Z

Make it possible to easily customize U-Boot config options via new `UBOOT_CUSTOMIZE_CONFIG` variable, so we don't need to patch config files or override config step with shell hackery. This generic approach uses `config` CLI to tweak the .config as needed, for example: UBOOT_CUSTOMIZE_CONFIG := \ --enable CMD_EFIDEBUG \ --enable CMD_BOOTMENU \ --enable AUTOBOOT \ --enable AUTOBOOT_MENU_SHOW \ --disable AUTOBOOT_KEYED \ --disable AUTOBOOT_USE_MENUKEY \ --disable BOOTMENU_DISABLE_UBOOT_CONSOLE \ --set-val BOOTDELAY 2 Signed-off-by: Petr Štetiar

u-boot.mk: add LOCALVERSION (explicitly specify OpenWrt build)

2022-02-28T22:54:52Z

For debugging purposes, we need to know if users are using modified U-boot versions or not. Currently, the U-boot version is somehow stripped. This is a little bit problematic when there are backported/wip/to-upstream patches. To make it more confusing, there was (before this commit) two U-boot versioning. U-boot compiled by OpenWrt build bots are missing ``Build:`` This is also the case when the U-boot is compiled locally. Example: ``` U-Boot SPL 2022.01 (Jan 27 2022 - 00:24:34 +0000) U-Boot 2022.01 (Jan 27 2022 - 00:24:34 +0000) ``` On the other hand, if you run full build, you can at least see, where it was compiled. Notice added ``Build:``. Example: ``` U-Boot 2022.01 (Jan 27 2022 - 00:24:34 +0000), Build: jenkins-turris-os-packages-burstlab-omnia-216 ``` In both cases, it is not clear to U-boot developers if it is an unmodified build. This is also caused that there is a missing ``.git`` file from U-boot folder, and so there is no history. It leads to that it can not contain suffix ``-dirty`` (uncommitted modifications) or even something else like number of commits, etc. [1] When U-boot is compiled as it should be, the version should look like this: ``U-Boot 2022.04-rc1-01173-g278195ea1f (Feb 11 2022 - 14:46:50 +0100)`` The date is not changed daily when there are new OpenWrt builds. This commit adds OpenWrt specific version, which could be verified by using strings. ``` $ strings bin/targets/mvebu/cortexa9/u-boot-omnia/u-boot-spl.kwb | grep -E "OpenWrt*" U-Boot SPL 2022.01-OpenWrt-r18942+54-cbfce92367 (Feb 21 2022 - 13:17:34 +0000) arm-openwrt-linux-muslgnueabi-gcc (OpenWrt GCC 11.2.0 r18942+54-cbfce92367) 11.2.0 2022.01-OpenWrt-r18942+54-cbfce92367 U-Boot 2022.01-OpenWrt-r18942+54-cbfce92367 (Feb 21 2022 - 13:17:34 +0000) ``` [1] https://u-boot.readthedocs.io/en/latest/develop/version.html Reported-by: Pali Rohár Suggested-by: Karel Kočí Signed-off-by: Josef Schlehofer
