2022-01-11kbuild: Add -m to DT_CHECKER_FLAGSHEADmasterLaurent Pinchart
The -m option to the DT checks catches additional errors. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-09-20kbuild: Remove unused options from help textLaurent Pinchart
The --no-dt, --no-image and --no-modules options have incorrectly been added to the help text. Remove them. Fixes: e7385853e45b ("kbuild: Add options to selectively compile kernel components") Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-09-20kbuild: Add an option to run DT bindings checksLaurent Pinchart
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-09-20kbuild: Allow adding out-of-tree DTBs to imageLaurent Pinchart
It's useful to build a FIT image with DTBs stored outside of the kernel tree, for instance to test vendor-supplied DTBs. Support this by allowing DTB paths to be absolute. Compilation of the DTB is skipped in that case. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-06-17kbuild: Support directory names in DTB destinationsLaurent Pinchart
The kbuild.sh script strips the directory name from the DTB destination. This is correct when no destination is specified explicitly, as we want to strip the directory name of the source for arm64 platforms where DT sources are stored in per-vendor directories. However, in some cases, we want to store the DTB in a sub-directory. A common use case is Raspberry Pi platforms that store overlays in an overlays/ subdirectory. Make this possible by stripping the directory name only when the destination is implicit. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-06-17kbuild: Avoid false matches in directory patternLaurent Pinchart
Require matches for the directory pattern to be a full directory name, to reduce the risk of false matches. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-05-12kbuild: Fix DT buildLaurent Pinchart
Introduction of the kernel component selection build option broke DT build. Fix it. Fixes: e7385853e45b ("kbuild: Add options to selectively compile kernel components") Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-04-24kbuild: FIT: Support custom load address for DTBLaurent Pinchart
This is required to merge overlays, as the base DTB needs to be relocated. Only the base address needs to be specified by platforms, addresses for all DTBs are calculated automatically. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-04-24kbuild: FIT: Add basic overlay supportLaurent Pinchart
Include DT overlays specified by the platform in the FIT image. Overlay compilation should ideally be handled by kbuild, but as a first step, the overlay files have to be manually copied to the output directory. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-04-24kbuild: Add variables for kernel root and kernel output directoriesLaurent Pinchart
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-03-10images: FIT: Support empty fit_conf_prefixLaurent Pinchart
If fit_conf_prefix is unset, "conf-" is used as a default prefix. This also applies if fit_conf_prefix is set but null. Support null fit_conf_prefix. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-03-10images: FIT: Fix board nameLaurent Pinchart
The board name is stored in $platform, not $board. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-03-10kflash: Don't rebuild imageLaurent Pinchart
There's no need to rebuild the image in kflash, we only need to source the image type support script to get the correct image file name. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-03-10kflash: Use lsblk instead of blkidLaurent Pinchart
lsblk doesn't require root permisions. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-03-10kflash: Use block device LABEL attribute if PARTLABEL isn't availableLaurent Pinchart
If the partition table doesn't support labels, use the filesystem label as a fallback. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-03-10kflash: Fix flash partition label checkLaurent Pinchart
When checking labels for flash partitions, the partition device is created with an incorrect (and unset) variable name for the partition index. Fix it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-02-16kbuild: Add --help argumentLaurent Pinchart
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-12-14images: FIT: Make configuration name configurableLaurent Pinchart
Not all boot loaders use the same naming scheme for configurations. Make the configuration name prefix configurable by platforms. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-12-14kbuild: Allow building documentation subsetsLaurent Pinchart
Add an optional argument to the --doc option to select documentation directories to build. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-12-14kbuild: Run documentation build in virtualenvLaurent Pinchart
To avoid depending on the sphinx version installed on the host, run the documentation build in a python virtual environment. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-12-14kbuild: Pass build options to bindeb-pkgLaurent Pinchart
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-09-02Support overriding the image file nameLaurent Pinchart
Add support for overriding the image file name, using the same mechanism as for DTB files. The 'image' parameter can specify both the image make target and image destination file name, separated by a ':'. If no ':' is found, the image make target is used as the image destination file name. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-09-02kbuild: Support custom make arguments on the command lineLaurent Pinchart
Add support for passing additional arguments to make. The arguments can be specified after the platform name, or, if no platform name is specified, after an empty option (--). Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-09-02kflash: Add argument to select which partitions to flashLaurent Pinchart
The --partitions argument can be used to select which partitions to flash. By default kflash will flash all partitions defined in the platform file. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-02-26platforms: zynqmp: Use a FIT imageLaurent Pinchart
This is more convenient as it combines the kernel and device tree. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-02-26platforms: Add target partition patterns to the CrOS platformsLaurent Pinchart
This enables kflash.sh support. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-02-26Add a kflash.sh flashing scriptLaurent Pinchart
The script eases flashing a kernel, modules and DT to a removable device. It detects the device based on partition name patterns defined in platform files, performs sanity checks to avoid overwriting system disks (such as making sure none of the target partitions are already mounted), copies files to raw partitions with dd or to file systems with cp or rsync, and beeps when done. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-02-26kbuild.sh: Don't disable the implicit-fallthrough warning by defaultLaurent Pinchart
This was done due to the latest stable version of the kernel not having implicit-fallthrough warnings fixed for ARM architectures. Now that this has been fixed, enable the warning again. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2020-02-18platforms: imx7: Add -Wno-error for BSP kernelsLaurent Pinchart
Use the new extra_kcflags mechanism to disable treating warnings as errors for BSP kernels. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-02-18Add simple mechanism to specify version-based extra CFLAGSLaurent Pinchart
Platform files can specify extra CFLAGS by extending the kcflags environment variable. When a kernel tree for a platform contains both BSP and mainline branches, different CFLAGS may be needed, as BSPs are usually littered with warnings. Make it possible to specify extra CFLAGS per kernel version through a new extra_kcflags array. This mechanism can be extended later if needed by storing version comparison strings as array keys (e.g. "<=4.19"). Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-09-05platforms: zynqmp: Update loadaddr for ZCU106Laurent Pinchart
The loadaddr specified for the zynqmp platform is invalid for the ZCU106. While the Image format doesn't make use of loadaddr, in preparation for a later switch to a FIT image, update the loadaddr already. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-08-22Ignore implicit fallthrough warningLaurent Pinchart
The kernel has enabled the implicit fallthrough warning without fixing all warnings on ARM first. Disable the warning until this gets addressed. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
