Checking the build files, the *.static.mtd.all.tar contains the 
image-bmc, manifest and signature files so yeah we can just upload that 
file without any build changes, we just need to add the support in the 
bmc-code-mgmt repo.

Looks good, if you could just break the patch into two separate patches, 
one for the supporting image-bmc and one for adding the ApplyTime 
property, and submit via gerrit as Lei YU pointed. Let us know if you 
have any questions with the process. Thanks!
