doc: android: document the AVB root key source

2026-08-12T07:44:24Z

The root-key choice carries security pitfalls that are not obvious from the Kconfig prompts alone: the built-in key is only a test key, a digest stored as a TEE persistent value is worthless unless the TA refuses to overwrite it while the device is unlocked, and the board provider must fail closed. Spell these out so an integrator does not ship an insecure default by accident.

doc: Switch from printenv to env print

2026-07-27T16:50:28Z

The "env" command is the recommended environment management command, its "print" subcommand is the equivalent replacement for legacy "printenv" command. Update the documentation to use the contemporary "env print" command instead of legacy "printenv" command. Note that the "printenv" command is unlikely to be removed from U-Boot in the near future due to it being integral part of the command line ABI. Implemented using: $ sed -i 's@\@env print@g' $(git grep -li '\' doc/) README Signed-off-by: Marek Vasut

doc: android: refresh AVB provenance and pin libavb reference

2026-07-27T12:26:32Z

Note that verification is performed by the libavb copy vendored under lib/libavb/ (AVB version 1.3.0) and which parts are U-Boot-specific, and pin the README reference to the exact upstream commit the vendored copy corresponds to instead of a moving master branch. Signed-off-by: Igor Opaniuk

cmd: fastboot: Add keyed abort option

2026-06-26T09:12:22Z

Works the same as CONFIG_CMD_UMS_ABORT_KEYED does: any keypress will abort fastboot mode (rather than only ctrl-c).

drivers: fastboot: Add support for SPI flash memory

2025-07-22T17:30:14Z

Fastboot currently supports MMC and NAND flash devices. Similarly, extend the support to SPI flash memories. Note that in this initial implementation, partitions on the device are not supported yet, but raw partitions can be set in U-Boot environment. To define a raw partition descriptor, add an environment variable similar to the MMC case: ``` fastboot_raw_partition_= ``` for example: ``` fastboot_raw_partition_boot=0x0 0x1000000 ``` Signed-off-by: Ariel D'Alessandro Reviewed-by: Mattijs Korpershoek

treewide: bcb: move ab_select command to bcb subcommands

2024-10-24T07:45:55Z

To enhance code organization, it is beneficial to consolidate all A/B BCB management routines into a single super-command. The 'bcb' command is an excellent candidate for this purpose. This patch integrates the separate 'ab_select' command into the 'bcb' group as the 'ab_select' subcommand, maintaining the same parameter list for consistency.
