This is not needed and we should avoid typedefs. Use the struct instead. Signed-off-by: Simon Glass <[email protected]>
2022-08-04sh: Remove unused code in arch/sh/lib/bootm.cTom Rini
There are no callers of the hexdump function that is guarded by CONFIG_SYS_DEBUG, so remove the section. Signed-off-by: Tom Rini <[email protected]>
2022-06-23linker_lists: Rename sections to remove . prefixAndrew Scull
Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters.

2022-02-09dts: automatically build necessary .dtb filesRasmus Villemoes
When building for a custom board, it is quite common to maintain a private branch which include some defconfig and .dts files. But to hook up those .dts files requires modifying a file "belonging" to upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch to a newer upstream then often results in a conflict which, while it is trivial to resolve by hand, makes it harder to have a CI do "try to build our board against latest upstream". The .config usually includes information on precisely what .dtb(s) are needed, so to avoid having to modify the Makefile, simply add the files in (SPL_)OF_LIST to dtb-y. A technicality is that (SPL_)OF_LIST is not always defined, so rework the Kconfig symbols so that (SPL_)OF_LIST is always defined (when (SPL_)OF_CONTROL), but only prompted for in the cases which used to be their "depends on". nios2 and microblaze already have something like this in their dts/Makefile, and the rationale in commit 41f59f68539 is similar to the above. So this simply generalizes existing practice. Followup patches could remove the logic in those two makefiles, just as there's potential for moving some common boilerplate from all the arch/*/dts/Makefile files to the new scripts/Makefile.dts.

2021-12-27Finish conversion of CONFIG_SYS_CLK_FREQ to KconfigTom Rini
In order to finish moving this symbol to Kconfig for all platforms, we need to do a few more things. First, for all platforms that define this to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk() and updating a few preprocessor tests. With that done, all platforms that define a value here can be converted to Kconfig, and a fall-back of zero is sufficiently safe to use (and what is used today in cases where code may or may not have this available). Make sure that code which calls this function includes <clock_legacy.h> to get the prototype. Signed-off-by: Tom Rini <[email protected]>

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler
Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler <[email protected]> Reviewed-by: Simon Glass <[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]>

2019-09-02sh: Fix OF_SEPARATE supportMarek Vasut
If the OF_SEPARATE is enabled, the DT is appended past the _end symbol. The current code however clears BSS very early, which overwrites the DT blob with zeroes.
