4 daysdrivers: sysreset: revert support for args in requestQuentin Schulz
This reverts: - commit e49c84f7bb7b ("doc: usage: cmd: reset: specify when the -edl option is available") - commit 1076feb8a3f9 ("cmd: boot: fix edl being shown when not supported") - commit 63c806ba0e12 ("qcom_defconfig: enable psci based sysreset") - commit ef06c5d76ff4 ("cmd: boot: Add '-edl' option to reset command documentation") - commit 32825eaddc37 ("sysreset: Implement PSCI based reset to EDL mode for QCOM SoCs") - commit fcb48b89813b ("drivers: sysreset: Add sysreset op that can take arguments") There was a conflict reverting commit 63c806ba0e12 ("qcom_defconfig: enable psci based sysreset") due to commit 02ef1859b44f ("configs: Resync with savedefconfig"), but the conflict resolution was trivial. The args support for the sysreset uclass contains a logic bug. The first sysreset device implementing the request_arg callback will consume the args, not support the specified arg and thus return -EPROTONOSUPPORT which will stop the iteration over all sysreset devices. This is an issue if one has multiple sysreset devices and each with support for different (valid) args. If a sysreset device implements a -dummy argument and another -foo and a user calls reset -dummy from the U-Boot CLI, it'll depend on which sysreset device will be attempted first. If it is the one implementing -foo, it'll return it doesn't support the argument with -EPROTONOSUPPORT in which case the device implementing -dummy will never be attempted and instead we'll do a cold reset which is very likely not what's expected from the user. Casey suggested[1] we revert this and start from scratch again with a different implementation instead.

2026-05-18cmd: boot: fix edl being shown when not supportedQuentin Schulz
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.

2021-08-26cmd: boot: Update reset usage messageMichal Simek
The commit 573a3811edc8 ("sysreset: psci: support system reset in a generic way with PSCI") has added support for warm reset via PSCI but this hasn't been reflected in usage message and user has to look at the code how to run it. That's why update usage text to make this clear.

2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <[email protected]>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <[email protected]>
