Not all the boards pick the same version when scheduling FAFT

Project Member Reported by waihong@chromium.org, Jun 14 2016

Issue description

Check the dashboard: http://go/faft_bios_dashboard
The snapshot: https://screenshot.googleplex.com/PAMZegRDtzb

FAFT BIOS suite is scheduled nightly. Given the 6/13 result as an example, most of the boards picked the test version R53-8446.0.0; however, some boards, e.g. celes and veyron_mickey, picked the different test version R53-8444.0.0.

All boards should pick the same test version such that we can see a consistent result.
 
Dan, any idea about this bug?

The suite scheduler pulls the latest "good" ChromeOS build to run test:

[FaftBiosNightly]
run_on: nightly
hour: 16
suite: faft_bios
branch_specs: ==tot
firmware_ro_build_spec: firmware
test_source: cros
pool: faft-test
file_bugs: True
job_retry: True

tot here doesn't mean the latest build, it has to be a good build.
As an example, 
https://ubercautotest.corp.google.com/afe/#tab_id=view_job&object_id=67127407
https://ubercautotest.corp.google.com/afe/#tab_id=view_job&object_id=67127217

For cyan, 8466 is bad, and 8464 is good, so the suite job uses build 8464
For auron_paine, 8466 is good, so it's used.

Thanks for explanation. 

Is it possible to group the result per day, like using another view flag? It makes sense to view the nightly suite in this view.

Together with the  issue 608412 , the current layout is difficult to understand. Can't easy to figure out if the missing result is caused by bad build or other reason.
