-# Calculate the auxiliary firmware revision to be updated in the dev_id.json
-# file. It is calculated from the VERSION_ID field which currently has two
-# formats. The revision field is 4 bytes, the first two bytes represent the
-# count of commits from the tagging and next two bytes represent the version.
-# Both fields are represented in BCD encoded format, so 9999 is the maximum
-# value both fields can take. With the format "v2.1-216-ga78ace8", Petitboot
-# would display the firmware revision as "Firmware version: 2.01.02160000",
-# "0216" is count and the revision is "0000". With the format
-# "ibm-v2.0-10-r41-0-gd0c319e" Petitboot would display the firmware revision
-# as "Firmware version: 2.00.00100041", "0010" is count and the revision
-# is "0041".
