Add a call to bootm_final() before jumping to the kernel. This adds the "Starting kernel" message, bootstage tracking, board_quiesce_devices() and dm_remove_devices_active() which were not previously called on Nios2. Signed-off-by: Simon Glass <[email protected]>

2026-01-20nios2: 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: - Aligns the final section before _end 8-bytes by adding '. = ALIGN(8);' to the final section before the symbol. - Remove a now-spurious '. = ALIGN(x);' statement that was intended to provide the above alignments. - Ensure that we do have alignment by adding an ASSERT so that when not aligned we fail to link (and explain why).

2024-09-03lmb: do away with arch_lmb_reserve()Sughosh Ganu
All of the current definitions of arch_lmb_reserve() are doing the same thing -- reserve the region of memory occupied by U-Boot, starting from the current stack address to the ram_top. Introduce a function lmb_reserve_uboot_region() which does this, and do away with the arch_lmb_reserve() function. Instead of using the current value of stack pointer for starting the reserved region, have a fixed value, considering the stack size config value.

2024-09-03lmb: make LMB memory map persistent and globalSughosh Ganu
The current LMB API's for allocating and reserving memory use a per-caller based memory view. Memory allocated by a caller can then be overwritten by another caller. Make these allocations and reservations persistent using the alloced list data structure. Two alloced lists are declared -- one for the available(free) memory, and one for the used memory. Once full, the list can then be extended at runtime.

2024-02-27Kconfig: Centralize prompting for SYS_CONFIG_NAMETom Rini
Generally speaking, we do not prompt for this value and define it in the board specific Kconfig file. There are some valid use cases however today where we do prompt for this value, so instead of having this be done in a number of locations, do this at the top-level location only. This removes the question from a number of other locations and makes it consistent that when we do set the value directly, we always do it the same way. We don't need to specify the type, it's always string. Signed-off-by: Tom Rini <[email protected]>
2023-12-21Merge patch series "Complete decoupling of bootm logic from commands"Tom Rini
Simon Glass <[email protected]> says: This series continues refactoring the bootm code to allow it to be used with CONFIG_COMMAND disabled. The OS-handling code is refactored and a new bootm_run() function is created to run through the bootm stages. This completes the work. A booti_go() function is created also, in case it proves useful, but at last for now standard boot does not use this. This is cmdd (part d of CMDLINE refactoring) It depends on dm/bootstda-working which depends on dm/cmdc-working

2022-06-23linker_lists: Rename sections to remove . prefixAndrew Scull
Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters.

2022-02-09dts: automatically build necessary .dtb filesRasmus Villemoes
When building for a custom board, it is quite common to maintain a private branch which include some defconfig and .dts files. But to hook up those .dts files requires modifying a file "belonging" to upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch to a newer upstream then often results in a conflict which, while it is trivial to resolve by hand, makes it harder to have a CI do "try to build our board against latest upstream". The .config usually includes information on precisely what .dtb(s) are needed, so to avoid having to modify the Makefile, simply add the files in (SPL_)OF_LIST to dtb-y. A technicality is that (SPL_)OF_LIST is not always defined, so rework the Kconfig symbols so that (SPL_)OF_LIST is always defined (when (SPL_)OF_CONTROL), but only prompted for in the cases which used to be their "depends on". nios2 and microblaze already have something like this in their dts/Makefile, and the rationale in commit 41f59f68539 is similar to the above. So this simply generalizes existing practice. Followup patches could remove the logic in those two makefiles, just as there's potential for moving some common boilerplate from all the arch/*/dts/Makefile files to the new scripts/Makefile.dts.
