Using -rc2 with firefly-rk3288 defconfig I can only boot into SPL but not into full U-Boot. I am using the old documented way of dd'ing to sector 256 on SD (doc/README.rockchip).
Looking at include/configs/rk3288_common.h I also tried putting u-boot.img on a FAT partition, to no effect.
v2017.03 doesn't even show SPL working. v2017.01 worked okay.
Build log for -rc2: https://build.opensuse.org/build/Base:System:Staging/openSUSE_Factory_ARM/ar...
Can you try removing RETURN_TO_BROM (or imilsar) and adding CONFIG_SPL_OF_PLATDATA?
As an interim update I can share that latest master behaves slightly differently:
U-Boot SPL 2017.05-rc2-00053-g3c476d8 (Apr 21 2017 - 02:29:48) Returning to boot ROM...
compared to:
U-Boot SPL 2017.05-rc2 (Apr 20 2017 - 14:33:20)
Disabling the ROCKCHIP_SPL_BACK_TO_BROM option I get:
U-Boot SPL 2017.05-rc2-00053-g3c476d8 (Apr 21 2017 - 02:38:52) SPL: Unsupported Boot Device! SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
If I additionally enable SPL_OF_PLATDATA then I am back to the v2017.03 state of no serial output.
I just tested mainline with those two changes and it works for me. I pushed my patch to u-boot-rockchip/firefly-working. Can you try again?
Confirming that with your defconfig it fully works again.
I had instead run menuconfig and manually (un)selected the options. Maybe those options influence other defaults? I was at the same qoriq merge commit your branch is based off.
Here's a quick diff against master:

At least SERIAL looks important...
