dts: automatically build necessary .dtb files

2022-02-09T19:26:12Z

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.

Finish conversion of CONFIG_SYS_CLK_FREQ to Kconfig

2021-12-27T21:20:18Z

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 to get the prototype. Signed-off-by: Tom Rini

lmb: sh: Add arch_lmb_reserve()

2021-09-23T18:15:32Z

Add arch_lmb_reserve() implemented using arch_lmb_reserve_generic(). This architecture also needs to cover U-Boot with LMB before booting Linux. Signed-off-by: Marek Vasut Cc: Simon Goldschmidt Cc: Tom Rini

global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14Z

It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass

reset: Remove addr parameter from reset_cpu()

2021-03-02T19:03:02Z

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 Reviewed-by: Simon Glass
