boot: add support for button commands

2024-02-13T20:38:49Z

With the relatively new button API in U-Boot, it's now much easier to model the common usecase of mapping arbitrary actions to different buttons during boot - for example entering fastboot mode, setting some additional kernel cmdline arguments, or booting with a custom recovery ramdisk, to name a few. Historically, this functionality has been implemented in board code, making it fixed for a given U-Boot binary and requiring the code be duplicated and modified for every board. Implement a generic abstraction to run an arbitrary command during boot when a specific button is pressed. The button -> command mapping is configured via environment variables with the following format: button_cmd_N_name=

Kconfig: boot: Imply BOOTSTD_DEFAULT when BOOTSTD_FULL=y

We need BOOTSTD_DEFAULT when BOOTSTD_FULL is selected. Signed-off-by: Shantur Rathore

efi_loader: split unrelated code from efi_bootmgr.c

2024-01-17T07:40:25Z

Some code moved from cmd/bootefi.c is actually necessary only for "bootefi " command (starting an image manually loaded by a user using U-Boot load commands or other methods (like JTAG debugger). The code will never been opted out as unused code by a compiler which doesn't know how EFI boot manager is implemented. So introduce a new configuration, CONFIG_EFI_BINARY_EXEC, to enforce them opted out explicitly. Signed-off-by: AKASHI Takahiro

boot: CONFIG_CEDIT must depend on CONFIG_EXPO

2024-01-12T02:19:25Z

Building sandbox_defconfig with CONFIG_CMD_CEDIT=y CONFIG_EXPO=n fails with cmd/cedit.c:258:(.text.do_cedit_run+0x4c): undefined reference to `expo_apply_theme Fix the dependencies. Fixes: a0874dc4ac71 ("expo: Add a configuration editor") Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

boot: add support for fdt_fixup command in environment

2023-12-21T16:59:49Z

The "fdt" command is convenient for making small changes to the OS FDT, especially during development. This is easy when the kernel and FDT are loaded separately, but can be cumbersome for FIT images, requiring to unpack the image, manually apply overlays, etc. Add an option to execute a command "fdt_fixup" from the environment at the beginning of image_setup_libfdt() (after overlays are applied, and before the other fixups).

bootmeth: use efi_loader interfaces instead of bootefi command

2023-12-17T12:04:54Z

Now that efi_loader subsystem provides interfaces that are equivalent with bootefi command, we can replace command invocations with APIs. Signed-off-by: AKASHI Takahiro

bootstd: Introduce programmatic boot

2023-12-13T16:51:24Z

At present bootstd requires CONFIG_CMDLINE to operate. Add a new 'programmatic' boot which can be used when no command line is available. For now it does almost nothing, since most bootmeths require the command line. Signed-off-by: Simon Glass

boot: Make preboot and bootcmd require CMDLINE

2023-11-07T19:49:09Z

In order for a predefined "preboot" or "bootcmd" to be executed by the running system we must have a command line. Add CMDLINE as a dependency. Signed-off-by: Tom Rini

bootmeth_script: Depend on CMDLINE

2023-11-07T19:49:09Z

As this particular bootmeth requires the command line and assorted commands to function, make sure we have CMDLINE enabled. Signed-off-by: Tom Rini

boot: Move SYS_BOOTM_LEN to be by LEGACY_IMAGE_FORMAT

2023-11-07T19:49:09Z

This particular option is required for booting all image types, regardless of if we are starting an OS via command line or something else. Move the question for SYS_BOOTM_LEN to be by the question for LEGACY_IMAGE_FORMAT, as that's where our generic OS questions start. Signed-off-by: Tom Rini
