2023-07-17android_ab: Try backup booloader_messageJoshua Watt
Some devices keep 2 copies of the bootloader_message in the misc partition and write each in sequence when updating. This ensures that there is always one valid copy of the bootloader_message. Teach u-boot to optionally try a backup bootloader_message from a specified offset if the primary one fails its CRC check. Signed-off-by: Joshua Watt <[email protected]>
2023-07-17android_ab: Add option to skip decrementing triesJoshua Watt
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.

2021-11-11Create a new boot/ directorySimon Glass
Quite a lot of the code in common/relates to booting and images. Before adding more it seems like a good time to move the code into its own directory. Most files with 'boot' or 'image' in them are moved, except: - autoboot.c which relates to U-Boot automatically running a script - bootstage.c which relates to U-Boot timing Drop the removal of boot* files from the output directory, since this interfers with the symlinks created by tools and there does not appear to be any such file from my brief testing.
