Merge patch series "Fix logic of OF_OMIT_DTB and remove useless dts files"

2026-09-03T22:12:28+00:00

Tom Rini says: In this series we correct how we handle OF_OMIT_DTB so that we can in turn not have an empty or fake dts file in the tree, when we are building for the case where we would be omitting building the final part of the dtb for use anyhow. With the changes in the previous series, we can then correct the Kconfig logic around OF_OMIT_DTB and DEFAULT_DEVICE_TREE so that when we're omitting the device tree binary we don't try and build one anyhow. Finally, we can remove all of the empty / fake device tree sources we have, or in some cases have but never used. Link: https://lore.kernel.org/r/20260824195224.556419-2-trini@konsulko.com

Merge patch series "Correct behavior of BLOBLIST_PASSAGE_MANDATORY"

2026-09-03T22:12:28+00:00

Tom Rini says: When we have mandatory passage enabled, we don't allow the fdt address to still be overriden. This is mostly working today but there are corner cases where it could still be overriden. Correct that by enforcing that if we don't find the device tree in the bloblist (when BLOBLIST_PASSAGE_MANDATORY is enabled) we error out. With that done, we can rework how the vexpress64 and mandatory passage support works as it wasn't using the correct symbols either for this case.

arm: Drop unused dts files

2026-09-03T19:21:42+00:00

Now that we do not require device tree files to be built when OF_OMIT_DTB is set, we can remove a number of unused dts files. Reviewed-by: Peter Robinson - For RPi DTs Reviewed-by: Yao Zi Signed-off-by: Tom Rini

powerpc: drop qemu-ppce500 dts

Now that we are not building this device tree, we can drop it from the tree. Reviewed-by: Yao Zi Signed-off-by: Tom Rini

dts: Correct entry for OF_OMIT_DTB

2026-09-03T19:21:42+00:00

When we omit writing a device tree file is not something that should be prompted for but rather it should be selected when needed, and the "default y if ..." conditions should be used for when this should be enabled without being selected. Reviewed-by: Yao Zi Signed-off-by: Tom Rini

dts: Make DEFAULT_DEVICE_TREE depend on !OF_OMIT_DTB

2026-09-03T19:21:42+00:00

When we have configured the board to not omit a DTB as part of the build, we should not have to say that we still need to build a default DTB for the board. Reviewed-by: Yao Zi Signed-off-by: Tom Rini

dts: Correct behavior of OF_OMIT_DTB

2026-09-03T19:21:42+00:00

When we have enabled CONFIG_OF_OMIT_DTB, we really should then be not forcing a device tree to be built. This involves two things. First, when OF_SEPARATE is set, don't say we still need to build dts/dt.dtb. Second, our init_sp_bss_offset_check check can only cover the non-dtb portion.

vexpress64: Correct CONFIG symbol logic around device tree passage

2026-09-03T19:21:18+00:00

When we don't have BLOBLIST_PASSAGE_MANDATORY enabled, then we're being passed the device tree in some other manner, via OF_HAS_PRIOR_STAGE. Correct our logic around which symbols are used to guard what is generated / used and when. Reviewed-by: Raymond Mao Acked-by: Ilias Apalodimas Acked-by: Linus Walleij Signed-off-by: Tom Rini

lib/fdtdec.c: Disallow overriding BLOBLIST_PASSAGE_MANDATORY

2026-09-03T19:21:18+00:00

When we have CONFIG_BLOBLIST_PASSAGE_MANDATORY enabled, we don't allow the device tree address to be overridden. However, in fdtdec_setup() we had been allowing for various cases of not having found the device tree in the bloblist, or overriding it, to be possible. Add a check after the bloblist check such that if we have enabled BLOBLIST_PASSAGE_MANDATORY we return an error at that point. Acked-by: Raymond Mao Signed-off-by: Tom Rini
