Hi Lukasz,
Hmm, I don't see it applied to u-boot-dfu now. Do I need to add something ?
Thanks,
Alexey

Hi Alexey,
The "fastboot reboot-bootloader" command is defined to
re-enter into fastboot mode after rebooting into
bootloader. This command is usually used after updating
bootloader via fastboot.
This commit implements only a generic side of the
command - setting of the reset flag and then resetting.
Setting of the reset flag is implemented using __weak
fb_set_reboot_flag() function. The actual setting and
checking of the reset flag should be implemented by
a boot script and/or board/SoC specific code.

Changes in v3:
- return -ENOSYS from default fb_set_reboot_flag()
Changes in v2:
- return error in default fb_set_reboot_flag()

Applied to u-boot-dfu.
Thanks for patch!
