Details - I've been building some test builds for EA9500 for testing. and noticed that upgrading is broken some few weeks now.

This can be replicated using trunk as of June-20-2017. I also tried the trunk from today (June-23-2017) - I noticed there were upstream patches related to bcm47xxpart merged. I was hoping it would fix it but it is still broken.

The last build I have that worked is from April 20th. I'm not sure when it broke.
