I can confirm that this boots on rock2 with current master branch.
9b1b6d42256a4c2e59c803afdbf90d39371e61ba

It doesn't boot for me using rock2 on v2016.09 tag. I get:
U-Boot SPL 2016.09-00002-g690a8a3 (Sep 20 2016 - 10:47:44)
Trying to boot from MMC1

It continues to detect 2GB of ram. on master.

I get nervous with these memory changes. We found that some memory
parameters persisted through to linux and had the ability to cause
instability. I don't run have linux setup right now on my rock2, so I can't
test that.

I also wanted to test that the parameters detected via the new routine
matched those removed from the dts file. I tried enabling DEBUG but that
somehow caused no console output anymore (on master). I'm not sure what's
going on. I also tried doing some printfs but they had the same effect. It
looks like somehow the console init has moved and maybe isn't setup yet.
