microblaze: Rework TARGET_MICROBLAZE_GENERIC implementation

2026-03-23T13:58:47+00:00

As exposed by "make randconfig", some symbols such as
XILINX_MICROBLAZE0_PVR can be set without TARGET_MICROBLAZE_GENERIC but
have a transitive dependency on it. The easiest path of resolution here
is that since there is only one valid microblaze "board", rework that
symbol to be non-optional.

microblaze: Call bootm_final()

2026-03-18T19:17:34+00:00

Replace the open-coded printf and bootstage_mark_name with a call to
bootm_final(). This also adds board_quiesce_devices() and
dm_remove_devices_active() which were not previously called on
MicroBlaze.

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22+00:00

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

Merge patch series "Update linker scripts to ensure appended device tree is correctly aligned"

2026-01-20T18:07:25+00:00

Tom Rini  says:

This series builds on top of what Beleswar Padhi did in [1]. While
there's still discussion about the mkimage related parts, the linker
portion appears to the reliable path forward. An alternative that I had
mentioned before, and was part of previous discussions on this topic[2]
is in the end I believe not reliable enough. While we can take an output
file and pad it to where we think it needs to be, ultimately the linker
needs to place the symbol where we want it and if that isn't where we
pad to, we have a different problem. So what this series does (but each
commit message elaborates on the arch-specific linker scripts being
inconsistent) is make sure the linker script will place the required
symbol at 8-byte alignment, and then also use an ASSERT to fail the
build if this would not be true due to some unforseen event.

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

2026-01-20T18:07:15+00:00

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 adjusting the ALIGN(4) statement to be
  ALIGN(8) in the final section before the symbol.
- Ensure that we do have alignment by adding an ASSERT so that when not
  aligned we fail to link (and explain why).

dtc: Add Kconfig option to pad device tree blob

2025-06-20T01:00:09+00:00

This will allow arch(s) that use device tree blobs to pad the end of the
device tree so they can be modified by board files at run time. This will
help prevent errors such as FDT_ERR_NOSPACE from occurring.

The dtbs: target is almost identical in all architecture Makefiles.
All architecture Makefiles include scripts/Makefile.dts . Deduplicate
the dtbs: target into scripts/Makefile.dts . No functional change.
