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.

2021-08-01sandbox: Reduce keyed autoboot delaySimon Glass
The autoboot tests are a recent addition to U-Boot, providing much-needed coverage in this area. A side effect of the keyed autoboot test is that this feature is enabled in sandbox always. This changes the autoboot prompt and confuses the pytests. Some tests become slower, for example the vboot tests take about 27s now instead of 3s. We don't actually need this feature enabled to be able to run the tests. Add a switch to allow sandbox to turn it on and off as needed. Use this in the one test that needs it.

2021-07-06sandbox: cros-ec: Add tests for the Chromium OS EC PWM driverAlper Nebi Yasak
This patch adds a limited pulse-width modulator to sandbox's Chromium OS Embedded Controller emulation. The emulated PWM device supports multiple channels but can only set a duty cycle for each, as the actual EC doesn't expose any functionality or information other than that. Though the EC supports specifying the PWM channel by its type (e.g. display backlight, keyboard backlight), this is not implemented in the emulation as nothing in U-Boot uses this type specification. This emulated PWM device is then used to test the Chromium OS PWM driver in sandbox. Adding the required device node to the sandbox test device-tree unfortunately makes it the first PWM device, so this also touches some other tests to make sure they still use the sandbox PWM.
