2026-01-20arm: Update linker scripts to ensure appended device tree is alignedTom Rini
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: - Expands some linker sections to be more readable when adding a second statement to the section. - Aligns the final section before _end (for U-Boot) or _image_binary_end or __bss_end (for xPL phases) by 8-bytes by adding '. = ALIGN(8);' to 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). - Remove now-spurious '. = ALIGN(x);' statements that were intended to provide the above alignments.

2026-01-02kbuild: Bump the build system to 6.1Sughosh Ganu
Our last sync with the kernel was 5.1. We are so out of sync now, that tracking the patches and backporting them one by one makes little sense and it's going to take ages. This is an attempt to sync up Makefiles to 6.1. Unfortunately due to sheer amount of patches this is not easy to review, but that's what we decided during a community call for the bump to 5.1, so we are following the same guidelines here.

2025-04-11Merge patch series "Switch to using $(PHASE_) in Makefiles"Tom Rini
Tom Rini <[email protected]> says: This series switches to always using $(PHASE_) in Makefiles when building rather than $(PHASE_) or $(XPL_). It also starts on documenting this part of the build, but as a follow-up we need to rename doc/develop/spl.rst and expand on explaining things a bit. Link: https://lore.kernel.org/r/[email protected]
2025-04-11Kbuild: Always use $(PHASE_)Tom Rini
It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in.

2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <[email protected]> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.

2024-06-07arm: move _end to linker symbolsIlias Apalodimas
commit 6e2228fb052b ("Merge patch series "Clean up arm linker scripts") was cleaning up linker scripts for armv7 and v8 but was leaving _end and __secure_stack_start/end. commit d0b5d9da5de2 ("arm: make _end compiler-generated") was moving _end to be compiler generated. _end is defined as c variable in its own section to force the compiler emit relative a reference. However, defining those in the linker script will do the same thing since [0]. So let's remove the special sections from the linker scripts, the variable definitions from sections.c and define them as a symbols. It's worth noting that _image_binary_end symbol is now redundant and can be removed in the future. - SPL The .end section has been removed from the new binary [ 5] .end PROGBITS 00000000fffdf488 000000000002f488 0 0000000000000000 0000000000000000 0 1 [0000000000000003]: WRITE, ALLOC $~ bloat-o-meter kria_old/spl/u-boot-spl krina_new/spl/u-boot-spl add/remove: 0/0 grow/shrink: 0/0 up/down: 0/0 (0) Function old new delta Total: Before=115980, After=115980, chg +0.00% $~ readelf -sW kria_old/u-boot kria_new/u-boot | grep -w _end 12047: 000000000813a0f0 0 OBJECT GLOBAL DEFAULT 11 _end 12047: 000000000813a118 0 NOTYPE GLOBAL DEFAULT 11 _end $~ readelf -sW kria_old/spl/u-boot-spl kria_new/spl/u-boot-spl | grep -w _end 1605: 00000000fffdf488 0 OBJECT GLOBAL DEFAULT 5 _end 1603: 00000000fffdf498 0 NOTYPE GLOBAL DEFAULT 4 _end $~ readelf -sW old/u-boot new/u-boot | grep -w _end 8847: 0000000000103710 0 OBJECT GLOBAL DEFAULT 11 _end 8847: 0000000000103738 0 NOTYPE GLOBAL DEFAULT 11 _end $~ readelf -sW old_v7/u-boot new_v7/u-boot | grep -w _end 10638: 000da824 0 OBJECT GLOBAL DEFAULT 10 _end 10637: 000da84c 0 NOTYPE GLOBAL DEFAULT 10 _end - For both QEMU instances $~ bloat-o-meter old/u-boot new/u-boot add/remove: 0/0 grow/shrink: 1/0 up/down: 20/0 (20) Function old new delta version_string 50 70 +20 Total: Before=656915, After=656935, chg +0.00% [0] binutils commit 6b3b0ab89663 ("Make linker assigned symbol dynamic only for shared object") Signed-off-by: Ilias Apalodimas <[email protected]>

The help for CONFIG_MTD explains that it needs to be enabled for various things like NAND, etc to be available. It however then doesn't enforce this dependency and so if you have none of these systems present you still need to disable a number of options. Fix this by making places that select/imply one type of flash, but did not do the same, also do this for "MTD". Make boards which hadn't been enabling MTD already but need it now, do so. In a few places, disable CONFIG_CMD_MTDPARTS as it wasn't previously enabled but was now being implied. Signed-off-by: Tom Rini <[email protected]>
