In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

EFS v1 allowed Chromeboxes to verify RW without AP. EFS v2 will bring
the benefts to Chromebooks, which are:
- Reduce RO dependency and presence. Allow more code to be updated
in the fields.
- Remove jumptag and workarounds needed for late sysjump.
Major imporvements over v1 are:
- No A/B slot required.
- No signature in RW or public key in RO.
- Rollback-attack protection.
- Verifies only RW being used instead of whole RW section.
For battery-equipped devices, additional benefts are:
- Immediate boot on drained battery.
- Support recovery mode regardless of battery condition.
- Faster charge in S5/G3.
EC-Cr50 communication is based on the shared UART (go/ec-cr50-comm).
EFS2 is documented in go/ec-efs2.
