u-boot.git/include/android_ab.h, branch v2024.01 Unnamed repository; edit this file 'description' to name the repository. android_ab: Add option to skip decrementing tries 2023-07-17T19:39:55+00:00 Joshua Watt jpewhacker@gmail.com 2023-06-23T22:05:48+00:00 22cdb3f0f174e926071975cdc5157aa6526b67a7 It is is sometimes desired to be able to skip decrementing the number of tries remaining in an Android A/B boot, and instead just check which slot will be tried later. This can commonly be be the case for platforms that want to A/B u-boot itself, but are required to boot from a FAT MBR partition. In these cases, u-boot must do an early check that the MBR points to the correct A/B boot partition, and if not rewrite the MBR to point to the correct one and reboot. Decrementing the try count in this case is not desired because it means that each u-boot might constantly ping-pong overwriting the MBR and rebooting until all the retries are used up.

common: Implement A/B metadata 2019-07-24T17:16:29+00:00 Ruslan Trofymenko ruslan.trofymenko@linaro.org 2019-07-05T12:37:32+00:00 d65e8da92ee7d594226aeee04eb0bef5d60f8bda This patch determines the A/B-specific bootloader message structure that is the basis for implementation of recovery and A/B update functions. A/B metadata is stored in this structure and used to decide which slot should we use to boot the device. Also some basic functions for A/B metadata manipulation are implemented (like slot selection). The patch was extracted from commits [1], [2] with some coding style fixes.
