New tool called fastbootd is included into recovery image. 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[2] 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. Please note that boot script is expected to handle 'boot-fastboot' command in BCB and load into recovery mode. Bootloader must support[3] 'reboot fastboot' command which should reboot device into userspace fastboot to accomodate those changes. Another command that bootloader must support[3] is 'reboot recovery'. This command should simply reboot device into recovery mode. Changes since v2[5]: * Split patch 1 into two separate patches: * Patch 1 extends fastboot_set_reboot_flag arguments with reboot reason * Patch 2 adds new reboot reasons for fastbootd and recovery * Added name for fastboot_rebot_reason enum * Replaced switch inside fastboot_set_reboot_flag with table lookup * Moved fastboot_set_reboot_flag BCB implementation to separate file Changes since v1[4]: * Added missing handling of reboot commands for network protocol * Extended fastboot_set_reboot_flag command to accept reboot reason * Made former fastboot_set_flag function as an optional implementation of fastboot_set_reboot_flag which could be turned on by Kconfig [1] - https://source.android.com/devices/bootloader/fastbootd [2] - https://source.android.com/devices/bootloader/fastbootd#unified_fastboot_and_recovery [3] - https://source.android.com/devices/bootloader/fastbootd#modifications_to_the_bootloader [4] - http://patchwork.ozlabs.org/project/uboot/cover/cover.1590539734.git.roman.kovalivskyi@globallogic.com/ [5] - http://patchwork.ozlabs.org/project/uboot/cover/cover.1591254465.git.roman.kovalivskyi@globallogic.com/ Roman Kovalivskyi (3): fastboot: Extend fastboot_set_reboot_flag with reboot reason fastboot: Add support for 'reboot fastboot' command fastboot: Add default fastboot_set_reboot_flag implementation arch/arm/mach-meson/board-common.c | 6 +++- arch/arm/mach-rockchip/board.c | 6 +++- board/amazon/kc1/kc1.c | 6 +++- board/lg/sniper/sniper.c | 6 +++- board/ti/am57xx/board.c | 6 +++- board/ti/dra7xx/evm.c | 6 +++- drivers/fastboot/Kconfig | 9 ++++++ drivers/fastboot/Makefile | 1 + drivers/fastboot/fb_bcb_impl.c | 48 ++++++++++++++++++++++++++++++ drivers/fastboot/fb_command.c | 40 ++++++++++++++++++++++++- drivers/fastboot/fb_common.c | 2 +- drivers/usb/gadget/f_fastboot.c | 2 ++ include/fastboot.h | 14 ++++++++- net/fastboot.c | 2 ++ 14 files changed, 145 insertions(+), 9 deletions(-) create mode 100644 drivers/fastboot/fb_bcb_impl.c
