cmd: boot: fix edl being shown when not supported

2026-05-18T06:37:13Z

edl is implemented in the sysreset_ops.request_arg callback of the qcom-psci sysreset driver. That callback is only called from sysreset_request_arg() which is compiled only when CONFIG_SYSRESET_CMD_RESET_ARGS=y. Therefore, only show the edl option if that symbol is enabled. It is in a separate if block because any option but -w will only be handled when CONFIG_SYSRESET_CMD_RESET_ARGS=y as seen with the implementation in do_reset() in drivers/sysreset/sysreset-uclass.c.

cmd: part: support lookup by UUID

2026-05-12T13:52:01Z

The 'part' command currently allows looking up a partition only by its number or name. Extend the 'number', 'start', and 'size' subcommands to support looking up the partition via its UUID. Unlike names, UUIDs guarantee unique partition identification, avoiding ambiguity. The logic is updated to check if the provided string is a valid UUID before falling back to a name-based search. The help strings for these subcommands are updated accordingly. Signed-off-by: Dario Binacchi Reviewed-by: Simon Glass

- Fix UMS and eMMC HW partition selection

cmd: ums: Switch HW partition before block access

2026-04-29T08:32:04Z

An UMS session with eMMC device specifier "ums C mmc dev.part1,dev.part2" exposes the same eMMC HW partition 'part2' twice instead of exposing both HW partitions 'part1' and 'part2'. Fix this by switching the eMMC HW partition before block device read/write access. An eMMC is represented by a single struct blk_desc, with the currently selected HW partition being stored in this struct blk_desc. Each call to part_get_info_by_dev_and_name_or_num() with partition string dev[.partN] does trigger HW partition switch by calling blk_get_device_part_str() -> blk_get_device_part_str() -> get_dev_hwpart() -> get_dev_hwpart() -> blk_dselect_hwpart(). The ums_init() iterates over the device specifier string and calls part_get_info_by_dev_and_name_or_num() in a loop for each dev[.partN] entry used as the partition string. If the device specifier string contains more than one dev[.partN] partition strings for the same dev device, then it is the HW partition described in the last dev[.partN] partition string entry that is accessed for all dev device partition strings in the device specifier string, because that last dev[.partN] partition string entry was the last one that triggered blk_dselect_hwpart() call for that device. To access the expected HW partition for every dev[.partN] partition string entry, it is necessary to call blk_dselect_hwpart() before each block read or write. Store HW partition described for each dev[.partN] partition string in struct ums and use the stored value to make it so. The blk_dselect_hwpart() does test whether the currently selected HW partition is already configured in hardware and does not reconfigure the hardware if that is the case, therefore for the majority of block reads and writes, blk_dselect_hwpart() is a no-op with negligible performance impact. Example reproducer is listed below. The last sector of both eMMC HW BOOT partitions is populated with distinct test pattern and UMS is launched: " => mmc dev 1 1 ; mmc read $loadaddr 0x1fff 1 ; md $loadaddr 4 switch to partitions #1, OK mmc1(part 1) is current device MMC read: dev # 1, block # 8191, count 1 ... 1 blocks read: OK 84000000: 1234abcd 1234abcd 1234abcd 1234abcd ..4...4...4...4. => mmc dev 1 2 ; mmc read $loadaddr 0x1fff 1 ; md $loadaddr 4 switch to partitions #2, OK mmc1(part 2) is current device MMC read: dev # 1, block # 8191, count 1 ... 1 blocks read: OK 84000000: 567890ef 567890ef 567890ef 567890ef ..xV..xV..xV..xV => ums 0 mmc 1.1,1.2 UMS: LUN 0, dev mmc 1, hwpart 1, sector 0x0, count 0x2000 UMS: LUN 1, dev mmc 1, hwpart 2, sector 0x0, count 0x2000 " Read of the two block devices on host without this fix produces identical data present in HW BOOT partition 2: " $ dd if=/dev/sdX of=mmc-a.bin ; dd if=/dev/sdY of=mmc-b.bin $ hexdump -C mmc-a.bin | tail -n 3 | head -n 1 ; \ hexdump -C mmc-b.bin | tail -n 3 | head -n 1 003ffe00 ef 90 78 56 ef 90 78 56 ef 90 78 56 ef 90 78 56 |..xV..xV..xV..xV| 003ffe00 ef 90 78 56 ef 90 78 56 ef 90 78 56 ef 90 78 56 |..xV..xV..xV..xV| " Read of the two block devices on host with this fix produces the expected distinct data from either HW BOOT partition 1 or 2: " $ dd if=/dev/sdX of=mmc-a.bin ; dd if=/dev/sdY of=mmc-b.bin $ hexdump -C mmc-a.bin | tail -n 3 | head -n 1 ; \ hexdump -C mmc-b.bin | tail -n 3 | head -n 1 003ffe00 cd ab 34 12 cd ab 34 12 cd ab 34 12 cd ab 34 12 |..4...4...4...4.| 003ffe00 ef 90 78 56 ef 90 78 56 ef 90 78 56 ef 90 78 56 |..xV..xV..xV..xV| " Reported-by: Christoph Niedermaier Signed-off-by: Marek Vasut Reviewed-by: Simon Glass

Merge patch series "net: migrate NO_NET out of the networking stack choice"

2026-04-27T17:28:25Z

Quentin Schulz 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. Additionally, because I started the script with set -e set and because buildman has an exit code != 0 when it fails to build a board, and I have the summary printed (which is the second buildman call), I believe it means all builds passed. The summary is the following: aarch64: (for 537/537 boards) all +0.0 rodata +0.0 uniphier_v8 : all +1 rodata +1 u-boot: add: 0/0, grow: 1/0 bytes: 1/0 (1) function old new delta data_gz 10640 10641 +1 arm: (for 733/733 boards) all -0.0 rodata -0.0 uniphier_v7 : all -1 rodata -1 u-boot: add: 0/0, grow: 0/-1 bytes: 0/-1 (-1) function old new delta data_gz 11919 11918 -1 opos6uldev : all -3 rodata -3 u-boot: add: 0/0, grow: 0/-1 bytes: 0/-3 (-3) function old new delta data_gz 18778 18775 -3 uniphier_ld4_sld8: all -3 rodata -3 u-boot: add: 0/0, grow: 0/-1 bytes: 0/-3 (-3) function old new delta data_gz 11276 11273 -3 stemmy : all -20 rodata -20 u-boot: add: 0/0, grow: 0/-1 bytes: 0/-20 (-20) function old new delta data_gz 15783 15763 -20 As far as I could tell this data_gz is an automatically generated array when CONFIG_CMD_CONFIG is enabled.

simplify NET_LEGACY || NET_LWIP condition with NET condition

2026-04-27T17:26:40Z

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.

rename NET to NET_LEGACY

2026-04-27T17:26:40Z

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.
