2022-10-06common/board_f: introduce arch_setup_dest_addr()Ovidiu Panait
In order to move ppc-specific code out of setup_dest_addr(), provide an arch-specific variant arch_setup_dest_addr(), that can be used by architecture code to fix up the initial reloc address. It is called at the end of setup_dest_addr() initcall and the default implementation is a nop stub. Reviewed-by: Simon Glass <[email protected]> Signed-off-by: Ovidiu Panait <[email protected]>

With commit ce39ee28ec31 ("zynqmp: Do not place u-boot to reserved memory location"), the function board_get_usable_ram_top() is allocating MMU_SECTION_SIZE of about 2MB using lmb_alloc().

2021-04-27powerpc: introduce CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLDRasmus Villemoes
When flush_cache() is called during boot on our ~7M kernel image, the hundreds of thousands of WATCHDOG_RESET calls end up adding significantly to boottime. Flushing a single cache line doesn't take many microseconds, so doing these calls for every cache line is complete overkill. The generic watchdog_reset() provided by wdt-uclass.c actually contains some rate-limiting logic that should in theory mitigate this, but alas, that rate-limiting must be disabled on powerpc because of its get_timer() implementation - get_timer() works just fine until interrupts are disabled, but it just so happens that the "big" flush_cache() call happens in the part of bootm where interrupts are indeed disabled. [1] [2] [3] I have checked with objdump that the generated code doesn't change when this option is left at its default value of 0: gcc is smart enough to see that the ">=" comparison is tautologically true, hence all assignments to "flushed" are eliminated as dead stores. On our board, setting the option to something like 65536 ends up reducing total boottime by about 0.8 seconds.

2021-04-27allow opting out of WATCHDOG_RESET() from timer interruptRasmus Villemoes
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 <[email protected]>

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
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 <[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]>
