2023-08-09treewide: unify the linker symbol reference formatShiji Yang
Now all linker symbols are declared as type char[]. Though we can reference the address via both the array name 'var' and its address '&var'. It's better to unify them to avoid confusing developers. This patch converts all '&var' linker symbol refrences to the most commonly used format 'var'. Signed-off-by: Shiji Yang <[email protected]> Reviewed-by: Tom Rini <[email protected]>
2023-08-09treewide: rework linker symbol declarations in sections headerShiji Yang
1. Convert all linker symbols to char[] type so that we can get the corresponding address by calling array name 'var' or its address '&var'. In this way, we can avoid some potential issues[1]. 2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has not been referenced by any source code. 3. Move '__data_end' to the arch x86's own sections header as it's only used by x86 arch. 4. Remove some duplicate declared linker symbols. Now we use the standard header file to declare them. [1] This patch fixes the boot failure on MIPS target.

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]>

2021-09-23lmb: Always compile arch_lmb_reserve() into U-Boot on arcMarek Vasut
The arch_lmb_reserve() is called by lib/lmb.c lmb_reserve_common() even if CMD_BOOTM is not enabled. However, the arc variant of arch_lmb_reserve() is only compiled in if CMD_BOOTM is enabled. This currently does not trigger build error, because there is an empty weak implementation of arch_lmb_reserve(), however that is not the function that should be used on arc. Fix this by moving the arch_lmb_reserve() implementation into common code and always compile it in.

2021-06-23global_data: Ensure we have <config.h> when symbols are not in Kconfig yetTom Rini
All symbols that are defined in Kconfig will always be defined (or not) prior to preprocessing due to the -include directive while building. However, symbols which are not yet migrated will only be defined (or not) once the board config.h is included, via <config.h>. While the end goal must be to migrate all symbols, today we have cases where the size of gd will get mismatched within the build, based on include order. Mitigate this by making sure that any <asm/global_data.h> that uses symbols not in Kconfig does start with <config.h>. Remove this when not needed.

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]>

This adds SoC-specific compatible strings to all users of the designware spi device. This will allow for the correct driver to be selected for each device. Where it is publicly documented, a compatible string for the specific device version has also been added. Devices without publicly-documented device versions include MSCC SoCs, and Arc Socs. All compatible strings except those for SoCFPGAs and some of the versioned strings have been taken from Linux. Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly necessary.
