assemble_cvd: Support quiescent boot for U-Boot#2877
Merged
Conversation
The prebuilt U-Boot bootloader in Cuttlefish TV lacks quiescent boot support
because it does not read the 'boot-quiescent' command from the BCB partition.
Inject a check into the U-Boot environment script ('uenvcmd') during assemble_cvd.
If 'boot-quiescent' is detected in BCB, append 'androidboot.quiescent=1' to kernel
bootargs and clear the BCB command.
