* Merge patch series "Complete decoupling of bootm logic from commands"Tom Rini2023-12-212-2/+10
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simon Glass <sjg@chromium.org> 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
| * bootm: Adjust arguments of boot_os_fnSimon Glass2023-12-211-2/+3
| | | | | | | | | | | | | | | | | | | | Adjust boot_os_fn to use struct bootm_info instead of the separate argc, argv and image parameters. Update the handlers accordingly. Few of the functions make use of the arguments, so this improves code size slightly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

| | | | | | | | | | | | | | | | | | | | | | The current do_reset() is called from a command context. Add a function which can be used from anywhere, as is done on ARM. Since there are lots of reset functions, this one actually just calls do_reset(). Future refactoring could correct this.

While as much dead code has been removed as possible, some of these locations are simply less obvious at first.

* allow opting out of WATCHDOG_RESET() from timer interruptRasmus Villemoes2021-04-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Having WATCHDOG_RESET() called automatically from the timer interrupt runs counter to the idea of a watchdog device - if the board runs into an infinite loops with interrupts still enabled, the watchdog will never fire. When using CONFIG_(SPL_)WDT, the watchdog_reset function is a lot more complicated than just poking a few SOC-specific registers - it involves accessing all kinds of global data, and if the interrupt happens at the wrong time (say, in the middle of an WATCHDOG_RESET() call from ordinary code), that can end up corrupting said global data. Allow the board to opt out of calling WATCHDOG_RESET() from the timer interrupt handler by setting CONFIG_SYS_WATCHDOG_FREQ to 0 - as that setting is currently nonsensical (it would be compile-time divide-by-zero), it cannot affect any existing boards. Add documentation for both the existing and extended meaning of CONFIG_SYS_WATCHDOG_FREQ. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

* treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada2020-07-172-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-079-19/+9
| | | | | | | | | | | | | | | | | | | | 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 <trini@konsulko.com>
