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 <trini@konsulko.com>
2021-12-27CONFIG_SYS_CLK_FREQ: Consistently be static or get_board_sys_clk()Tom Rini
This CONFIG option is used in one of two ways. The first way is that it is defined to a static value, of an unsigned long size. The second way is that it is defined to something, typically a function, to determine this value at run time. However, in a few cases that function returns a static value. Change that to using the static value directly. In the case of using something at run time, convert everything to using a function of the same name and prototype. This will allow for further cleanups. Finally, we have a few cases where the function is just not used, so drop it. Signed-off-by: Tom Rini <trini@konsulko.com>

2021-12-27Finish converting CONFIG_SYS_FSL_CLK to KconfigTom Rini
This converts the following to Kconfig: CONFIG_SYS_FSL_CLK We move the exiting option to common/Kconfig near the other options to control the contents of board_init_f() and note that this is a legacy option. We further restrict this to where the call is going to be non-empty, for the SoCs that had only been using this for some MMC-related clocks. Signed-off-by: Tom Rini <trini@konsulko.com>
2021-12-27warp7, pic32mzdask: Remove SYS_FDT_ADDR/SYS_ENV_ADDR from CONFIG namespaceTom Rini
In the case of CONFIG_SYS_FDT_ADDR this was being used to modify the default value of fdt_addr / fdt_addr_r, which is not something to expose in this manner and is not otherwise done. The case of SYS_ENV_ADDR is similar but only done on the pic32mzdask platform, for scriptaddr. Signed-off-by: Tom Rini <trini@konsulko.com>

To make the Kconfig logic clearer, guard all of the sub-options with a if VID || SPL_VID check. Finally, add Kconfig options for the remaining related options that did not previously have one.

2021-12-27Convert CONFIG_SYS_IMMR to KconfigTom Rini
This converts the following to Kconfig: CONFIG_SYS_IMMR We do this by consolidating the SYS_IMMR options we have and providing defaults. We also, in the few places where M68K was also sharing code with these platforms, define it within the file to CONFIG_SYS_MBAR to match usage. This should be cleaned up longer term.

2021-12-27Finish converting CONFIG_WATCHDOG, HW_WATCHDOG and WDT to KconfigTom Rini
Because of how these symbols work, and the remaining board config.h file uses, we need to do these at the same time. In some cases we just get to move rather directly to the defconfigs. A few cases require manual intervention. For the case of the eb_cpu5282 we need to select HW_WATCHDOG for the target, given how it's implemented. For the cases of m53menlo, dh_imx6, display5, and display5_factory we disable SPL watchdog support as the particular combination of options they want would require either more symbols or enabling SPL_DM.

2021-12-24Merge branch '2021-12-23-make-OF_BOARD-a-boolean' into nextTom Rini
Merge v8 of Simon's series to make CONFIG_OF_BOARD a boolean option. Quoting him: With Ilias' efforts we have dropped OF_PRIOR_STAGE and OF_HOSTFILE so there are only three ways to obtain a devicetree: - OF_SEPARATE - the normal way, where the devicetree is built and appended to U-Boot - OF_EMBED - for development purposes, the devicetree is embedded in the ELF file (also used for EFI) - OF_BOARD - the board figures it out on its own The last one is currently set up so that no devicetree is needed at all in the U-Boot tree. Most boards do provide one, but some don't. Some don't even provide instructions on how to boot on the board. The problems with this approach were covered in another patch[1], since removed from this series. In practice, OF_BOARD is not really distinct from OF_SEPARATE. Any board can obtain its devicetree at runtime, even it is has a devicetree built in U-Boot. This is because U-Boot may be a second-stage bootloader and its caller may have a better idea about the hardware available in the machine. This is the case with a few QEMU boards, for example. So it makes no sense to have OF_BOARD as a 'choice'. It should be an option, available with either OF_SEPARATE or OF_EMBED. This would allow rpi3, for example, to run with the devicetree provided by the prior bootloader. This series makes this change, adding various missing devicetree files (and placeholders) to make the build work. To make the 'prior stage' side of things more deterministic, a new OF_HAS_PRIOR_STAGE is added, which cannot be disabled by updated a board's defconfig. This should help to prevent mistakes. It also adds a run-time message showing where the devicetree came from, as well as warnings if the board's expected flow is not being used. This comes originally from the 'standard passage' series, which depends on this series. It also provides a few qemu clean-ups discovered along the way. The qemu-riscv64_spl problem is fixed. Please see [2] for discussion on the v6 series. I put Heinrich's Tested-by tag[3] for the series onto the three devicetree patches (ARM and RISC-V) that I think it most affects. It isn't possible to apply a tag to a whole series at present and in any case there are changes in v7. This series is available at u-boot-dm/ofb-working [1] https://patchwork.ozlabs.org/project/uboot/patch/20211207001209.3467163-2-sjg@chromium.org/ [2] https://lore.kernel.org/u-boot/20211205133207.GW1220664@bill-the-cat/T/#mcd8c0258827fbc1bb3000b7ff9ba0929df1ddcb2 [3] https://lore.kernel.org/u-boot/93913911-4d20-d28f-ee04-739985184c5e@canonical.com/raw
2021-12-23fdt: Show a runtime warning based on devicetree sourceSimon Glass
When running, if the devicetree failed to come from the expected source, show a warning, e.g: U-Boot ... DRAM: 128 MiB Core: 42 devices, 11 uclasses, devicetree: separate Warning: Unexpected devicetree source (not from a prior stage) Warning: U-Boot may not function properly Flash: 64 MiB ...

2021-12-23fdt: Avoid emitting an device tree when not neededSimon Glass
U-Boot always needs some sort of a device tree in the build. Some boards never actually use this, at least in production systems, since a prior firmware stage sets one up and passes it to U-Boot. At present the only mechanism to do that is with custom function (OF_BOARD), but future work will include a standard way of doing this ('standard passage'). It can be confusing to see a device tree emitted from the U-Boot build in this situation. Add an option to drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-12-23fdt: Makefile: Ensure that OF_BOARD is used when neededSimon Glass
Boards which define OF_HAS_PRIOR_STAGE must define OF_BOARD at present, since a custom function is the only way to obtain the devicetree at runtime. Add a build error when this requirement is not met, to avoid accepting any patches which break this requirement. Add an allowlist for boards which use it, currently none. This allowlist can be updated for local development, if needed. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: change of_whitelist to of_allowlist] Signed-off-by: Tom Rini <trini@konsulko.com>
2021-12-23fdt: Enable OF_HAS_PRIOR_STAGE for most boards with OF_BOARDSimon Glass
Use this new Kconfig instead of OF_BOARD, so we know for sure which boards obtain their devicetree from a prior stage. Leave sandbox alone since it does not. Also don't touch xilinx_versal_virt since it does not have a specific TARGET Kconfig. This option implies OF_BOARD for now, but with future work standard passage may be used instead.

2021-12-23fdt: Add a Kconfig for boards with a prior stageSimon Glass
When U-Boot is started from another firmware program, not just a prior phase of U-Boot, special behaviour is typically used. In particular, the device tree may come from that prior stage. At present this is sort-of indicated by OF_BOARD, although the correlation is not 1:1, since that option simply means that the board has a custom mechanism for obtaining the device tree. For example, sandbox defines OF_BOARD. Also the board_fdt_blob_setup() function can in fact make use of the devicetree in U-Boot if it wishes, as used by dragonboard410c until very recently. Add an explicit Kconfig for this situation. Update the OF_BOARD option to more-accurately reflect what it is doing, e.g. for sandbox. Drop the docs in the README as it is out of date.

2021-12-23fdt: Report the devicetree sourceSimon Glass
It can be confusing to figure out where the devicetree came from. It seems important enough to warrant a message during boot. Add information about the number of devices and uclasses too since it is helpful to have some idea what is going on with driver model. Report the devicetree source in bdinfo too. This looks something like this, with > marking the new line.

2021-12-23fdt: Don't call board_fdt_blob_setup() without OF_BOARDSimon Glass
At present this override function is called even when OF_BOARD is not enabled. This makes it impossible to disable this feature and in fact makes the OF_BOARD option useless. Reinstate its intended purpose, so that it is possible to switch between the appended devicetree and one provided by the board's custom function. A follower patch adds warnings for this scenario, but for now we don't have a Kconfig that definitively tells us that OF_BOARD should be used. Signed-off-by: Simon Glass <sjg@chromium.org>
