android_bootable_recovery/partitionmanager.cpp
bigbiff df8436b51a fastboot: implement fastbootd in twrp 
fastbootd is a userspace daemon that runs in the recovery
ramdisk. It allows writing single partitions to the super
partition via fastboot CLI. When TWRP sees the fastboot option
in the misc partition during startup, it will start with
the fastbootd page and fastbootd running. Otherwise it will
run recovery normally.
