Zork: Enable EFS2
EFS v.1 allowed Chromeboxes to verify RW without AP. EFS v.2 will bring
the benefits to Chromebooks, which are:
- Immediate boot on deeply discharged battery.
- Faster charge in S5/G3.
- Reduce RO dependency. Allow more code to be updated by AU.
- Remove jumptag and workarounds needed for late sysjump.
- Can support recovery mode regardless of battery condition.
Major improvements over v.1 are:
- No A/B slot required.
- No signature in RW or public key in RO.
- Rollback-attack protection.
- Verifies only used part of RW (instead of whole RW section)
EC-Cr50 communication is based on the shared UART (go/ec-cr50-comm).
EFS2 is documented in go/ec-efs2.
