From 2b2a771b40876c3db456705d5dcc5b60249d4075 Mon Sep 17 00:00:00 2001 From: Roman Kovalivskyi Date: Tue, 28 Jul 2020 23:35:33 +0300 Subject: fastboot: Add support for 'reboot fastboot' command Android 10 adds support for dynamic partitions and in order to support this userspace fastboot must be used[1]. New tool fastbootd is included into recovery. Userspace fastboot works from recovery and is launched if: 1) - Dynamic partitioning is enabled 2) - Boot control block has 'boot-fastboot' value into command field The bootloader is expected to load and boot into the recovery image upon seeing boot-fastboot in the BCB command. Recovery then parses the BCB message and switches to fastbootd mode[2]. Please note that boot script is expected to handle 'boot-fastboot' command in BCB and load into recovery mode. Bootloader must support 'reboot fastboot' command which should reboot device into userspace fastboot to accomodate those changes[3]. Another command that bootloader must support[3] is 'reboot recovery'. This command should simply reboot device into recovery mode.
