2026-06-24common: Add an option to relocate on ram topIlias Apalodimas
Right now we only relocate u-boot to the top of the first memory bank unless the board specific code overwrites it. This is problematic when loading big binaries as it fragments the contiguous memory space for no apparent reason. On certain platforms, it is currently not possible to relocate U-Boot above the 32bit boundary, due to various dependencies on content located below the 32bit boundary. One such example is ethernet, where the packet buffer built into U-Boot binary is placed below the 32bit boundary and allows loading of data via ethernet even above 32bit boundary due to memory copy from the packet buffer to the destination location. A previous patch moves the bi_dram[] info from bd to gd and make the memory bank information available early. So move the dram_init_banksize() INITCALL before the relocation address calculation and use it to derive the address. Also add a Kconfig option and allow the common code to relocate U-Boot to the top of the last discovered bank. It's worth noting that this patch changes when dram_init_banksize() is called. It's now called much earlier in the board init process. That is a significant ordering change for every board with a custom dram_init_banksize(), and it is unconditional (not gated on RELOC_ADDR_TOP).

2026-06-24common: move ram_base calculation to independent INITCALL()Ilias Apalodimas
Currently, ram_base is calculated within setup_dest_addr(). However, upcoming patches that enable U-Boot relocation to the highest DRAM bank require ram_base to be initialized earlier. The default dram_init_banksize() definition relies on ram_base to calculate the start of the first bank. But following patches will move that function to execute immediately before setup_dest_addr(). So let's split the ram_base initialization in its own INITCALL.

2026-06-24treewide: move bi_dram[] from bd to gdIlias Apalodimas
Currently, the bi_dram[] information is stored in the board info structure (bd). Because bd is only valid after reserve_board(), dram_init_banksize() must be called late in the initialization process. This limitation is problematic, as it forces us to rely on a variety of bespoke functions to determine board RAM, bank memory sizes, and other early setup requirements. By moving bi_dram[] into the global data (gd), we can run it earlier. This is particularly convenient since boards define their own dram_init_banksize() routines, which do not always rely on parsing Device Tree (DT) memory nodes. Additionally, U-Boot defaults to relocating to the top of the first memory bank. While boards currently use custom functions to override this behavior, having the DRAM bank information available earlier in gd makes relocating to a different bank trivial and standardizes the process.

2026-06-17Merge patch series "Fixes, cleanup and a test for the SPL FIT "full" loader"Tom Rini
Francesco Valla <[email protected]> says: This patch set contains a collection of small fixes and cleanups for the "full" FIT loader that can be used for the SPL. The main beneficiary is the falcon boot flow, but the same loader can be used also for U-Boot proper. Patch 1 was part of another set, but I decided to put it here for a better separation between plumbing (here) and new features (there). I kept the Reviewed-by tag collected from Simon in that occasion. Patch 6 introduces a new unit test covering most of the code that is being cleaned up. The set was tested on a i.MX93 FRDM, both with and without signature and to boot both U-Boot proper and the Linux kernel directly (i.e., falcon boot).

2026-06-17Merge patch series "arm: omap: Add back omap4 support"Tom Rini
Bastien Curutchet <[email protected]> says: This series aims to add back the omap4 support. This support was removed by commit b0ee3fe642c ("arm: ti: Remove omap4 platform support") because at that moment, none of the OMAP4-based boards had done the migration to DM_I2C. My use case is an old product based on the Variscite's omap4 system on module. I needed to upgrade U-Boot on it for security reasons. I think that this work could benefit to other people who may have same kind of product to maintain. Patch 1 to 3 remove the omap's clock driver dependency to the AM33xx as it is also present in omap4 platforms. I tested these changes on the beaglebone black to ensure I didn't break the AM33xx case. Patch 4 & 5 revert the deletion of the omap4 support. The revert makes checkpatch.pl angry. I fixed quite a lots of warnings already but it remains two kinds of warnings: - CamelCase on timings structure, I left the CamelCase because IMHO it's more readable this way. - #ifdef CONFIG_XYZ shouldn't be used anymore. I left one of this because I didn't find a clean way to get rid of it. Patch 6 adds support for the Variscite's system on module. This system on module is supported by the Linux project through ti/omap/omap4-var-som-om44.dtsi Link: https://lore.kernel.org/r/[email protected]

omap4 support was dropped by b0ee3fe642c ("arm: ti: Remove omap4 platform support") because the supported boards hadn't done the conversion to CONFIG_DM_I2C in time. It still exists some omap4-based products and they could benefit from the latest U-Boot support for obvious security reasons.

Add a new global data struct member called initial_relocaddr. This stores the original value of relocaddr, directly from setup_dest_addr. This is specifically to avoid any adjustments made by other init functions. Reserve the memory from gd->start_addr_sp - CONFIG_STACK_SIZE to gd->initial_relocaddr instead of gd->ram_top.

2026-06-02Merge patch series "Clean up bloblist initialization"Tom Rini
Tom Rini <[email protected]> says: This series does a few small but important cleanups to how we check for, and initialize a bloblist. The first thing is that the way things are done today, our HANDOFF code can only work with a fixed bloblist location, so express that requirement in Kconfig. Next, we demote the scary message about "Bloblist at ... not found" to a debug because we most often see that because the bloblist doesn't (and can't) exist yet. Finally, we remove bloblist_maybe_init and split this in to an exists and a real init. This results in practically no growth (between 8 bytes growth to 12 bytes saved, with some outliers saving much more thanks to knowing it's impossible to have been passed a bloblist yet). This also cleans up some of the code around checking for / knowing about a bloblist existing. Link: https://lore.kernel.org/r/[email protected]
2026-06-02bloblist: Rework bloblist_init and bloblist_maybe_initTom Rini
With bloblist, we need to both see if one already exists as well as create one if it does not. However, the current implementation leads to odd cases where we attempt to create a bloblist before this is possible and have things be overly complicated when we are given one to work with. This reworks things to instead have a bloblist_exists function, which as the name implies checks for an existing bloblist. This is used in the case of booting, to see if we have one and in turn if we have a device tree there as well as in the bloblist_init function to see if we need to do anything. In practical details, we move the logic from bloblist_init that was checking for a bloblist to the new bloblist_exists function and then can clarify the logic as it is much easier to state when we know we do not have one rather than all the ways we might have one. Then we have the locations that set gd->bloblist now also set the GD_FLG_BLOBLIST_READY flag.

2026-05-04common: memsize: fix occasionally failing alias probingEmanuele Ghidoli
probe_ram_size_by_alias() detects whether a probe address still aliases a lower address by writing through one address and reading through the other. On i.MX95 this occasionally reported a false non-alias when the alias read happened immediately after the write. A memory barrier alone, mb(), was tested but did not make the failure go away. This suggests that ordering the CPU accesses is not sufficient for this probe, likely because the issue is in the path to the memory controller rather than in the core itself. Read the written address back before checking the alias address. This appears to force the write to become observable at the probe address before using the alias read to decide whether the tested address range exists. If the readback does not match the written pattern, restore the saved value and continue with the next check. This keeps the probe robust for addresses that do not reliably retain the test pattern.

Quentin Schulz <[email protected]> says: This migrates the net options away from the main Kconfig to net/Kconfig, rename the current NET option to NET_LEGACY to really highlight what it is and hopefully encourage more people to use lwIP, add a new NET menuconfig (but keep NO_NET as an alias to NET=n for now) which then allows us to replace all the "if legacy_stack || lwip_stack" checks with "if net_support" which is easier to read and maintain. The only doubt I have is wrt SYS_RX_ETH_BUFFER which seems to be needed for now even when no network is configured? Likely due to include/net-common.h with PKTBUFSRX? No change in behavior is intended. Only change in defconfig including other defconfigs where NO_NET=y or NET is not set, in which case NO_NET is not set or NET=y should be set in the top defconfig. Similar change required for config fragments. See commit log in patch adding NET menuconfig for details. This was tested based on 70fd0c3bb7c2 ("x86: there is no CONFIG_UBOOT_ROMSIZE_KB_12288"), from within the GitLab CI container trini/u-boot-gitlab-ci-runner:noble-20251013-23Jan2026 and set up similarly as in "build all platforms in a single job" GitLab CI job. #!/usr/bin/env bash set -o pipefail set -eux ARGS="-BvelPEWM --reproducible-builds --step 0" ./tools/buildman/buildman -o ${O} --force-build $ARGS -CE $* ./tools/buildman/buildman -o ${O} $ARGS -Ssd $* O=../build/u-boot/ ../u-boot.sh -b master^..b4/net-kconfig |& tee ../log.txt I can't really decipher the log.txt, but there's no line starting with + which would be an error according to tools/buildman/builder.py help text.

2026-04-27simplify NET_LEGACY || NET_LWIP condition with NET conditionQuentin Schulz
Since the move to make NET a menuconfig and NO_NET a synonym of NET=n, when NET is enabled, NET_LEGACY || NET_LWIP is necessarily true, so let's simplify the various checks across the codebase. SPL_NET_LWIP doesn't exist but SPL_NET_LEGACY is an alias for SPL_NET so the proper symbol is still defined in SPL whenever needed.

2026-04-27rename NET to NET_LEGACYQuentin Schulz
Highlight that NET really is the legacy networking stack by renaming the option to NET_LEGACY. This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL. The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is using the legacy networking app so this seems fine to do. This also has the benefit of removing potential confusion on NET being a specific networking stack instead of "any" network stack.

2026-04-24common: update: Fix TFTP return value handlingMarek Vasut
The net_loop() returns 1 on success, but update_load() returns 0 on success. Do not assign rv which is the return value of update_load() to net_loop(), instead assign net_loop() return value to a temporary variable and then update rv only if the temporary variable is negative. This way the update_load() now correctly returns 0 on tftp success and 1 only on failure. Signed-off-by: Marek Vasut <[email protected]>

2026-04-21common: memsize: add RAM size probe based on alias detectionEmanuele Ghidoli
Add probe_ram_size_by_alias() to detect RAM size by checking whether a write to one address aliases to another address. Compared to get_ram_size(), this function allows the caller to: - limit probing to a small set of required accesses - avoid touching reserved or already used memory regions - handle non-linear alias patterns On the iMX95 SoC, when used with LPDDR5, accesses beyond the end of an 8GB DDR configuration do not alias to the expected linear wrap-around addresses. Instead, the aliased addresses appear to follow a pattern related to the DDRC bank and bank-group addresses mapping. Experimentally, the observed pattern is: Write Read y00000000 -> x0001c000 y00004000 -> x00018000 y00008000 -> x00014000 y0000c000 -> x00010000 y00010000 -> x0000c000 y00014000 -> x00008000 y00018000 -> x00004000 y0001c000 -> x00000000 This helper makes it possible to probe RAM size by explicitly specifying the probed address and the expected alias address for each size check.

2026-04-21Merge patch series "Linux compat improvements and CCF prep"Tom Rini
Casey Connolly <[email protected]> says: This series implements various improvements to Linux header compatibility, largely in preparation for a full port of Linux CCF but many of these changes would also be helpful when porting other drivers. Beside the basic header/compat stuff there are a few larger patches: Patch 1 adds the "%pOF" format specifier to vsprintf, this behaves the same as it does in Linux printing the name of the ofnode, but notably it expects an ofnode pointer rather than a device_node. Patch 2 adds an option to skip doing a full DM scan pre-relocation. Some platforms like Qualcomm don't actually need devices to be probed prior to relocation, it is also quite slow to scan the entire FDT before caches are up. This option gets us to main loop 30-50% faster. Unfortunately it isn't possible to totally skip DM since U-Boot will panic if it can't find a serial port, but the serial uclass code will bind the serial port itself by reading /chosen/stdout-path, however any dependencies like clocks won't be found so this should only be enabled if the serial driver gracefully handles missing clocks. Patch 3 adds [k]strdup_const(), this works the same as the Linux version saving a small amount of memory by avoiding duplicating strings stored in .rodata, this is particularly useful for CCF. Patch 4 adds 64-bit versions of some 32-bit ofnode utilities functions, making it possible to parse 64-bit arrays. Patch 6 provides a simple implementation of kref, this will be used by CCF. Patch 9 adds devm_krealloc() support to devres, it relies on storing allocation sizes in the devres struct which will add a small overhead. Link: https://lore.kernel.org/r/[email protected]
2026-04-21common: add an option to skip DM pre-relocationCasey Connolly
For some platforms like Qualcomm, it isn't necessary to perform a full DM init and scan prior to relocation, it's also particularly slow since it runs with dcache disabled and prior to building the livetree. The only device which needs to be probed pre-reloc is the serial port (otherwise U-Boot will panic), however this can be found through /chosen/stdout-path. Therefore we can avoid scanning the entire FDT and binding devices, instead just binding the serial port and clock driver on-demand. This decreases the total time from power on to reaching the interactive U-Boot shell be about 50% (from ~2.8s to 1.8s). Signed-off-by: Casey Connolly <[email protected]>

2026-03-30console: Prefer currently selected serial console as stdio deviceMarek Vasut
Adjust the scan for default console stdio device to prefer the currently selected serial device. This is useful in combination with CONFIG_SERIAL_PROBE_ALL=y, in which case the system would instantiate all serial devices as stdio devices in the order in which they are listed in control DT. The currently selected serial device may not be the first device listed in DT, in which case the current console_init_r() implementation unexpectedly switches to another serial console after listing stderr using "Err:" line, and just before showing U-Boot shell, which is not the desired behavior. The scan now iterates over the entire list of stdio devices. If the current iterator stdio device is the current serial device, or there is no input or output stdio device assigned to the input or output stream yet, then the current iterator stdio device is assigned to that stream. This way, the first suitable stdio device is assigned to the stream, but the current serial console stdio device can override that assignment. As a small optimization, if the current iterator stdio device is the current serial device and both input and output streams as assigned, then the loop can terminate, because the current serial device has a chance to be used as a stdio device at this point.
