[iot] Support authenticated unlock
Add fastboot commands "fastboot oem at-get-vboot-unlock-challenge"
and "fastboot oem at-unlock-vboot" to support the authenticated
unlock feature for Android Things devices. Use software random
numbers generator to generate the 16 bytes random challenge, it
should be replaced with hardware encrypted random generator when
the TEE part is ready.
Test: Generate unlock challenge by:
./avbtool make_atx_unlock_credential
--output=atx_unlock_credential.bin
--intermediate_key_certificate=atx_pik_certificate.bin
--unlock_key_certificate=atx_puk_certificate.bin
--challenge=my_generated_challenge.bin
--unlock_key=testkey_atx_puk.pem
validated the unlock credential successfully on imx7d_pico
and AIY.
