I applied this series on top of current u-boot/master.

On Jetson TK1 (T124), I see the following errors when U-Boot starts:

I assume you can investigate that without issue, since you have that board.

On Jetson TX1 (T210), you need to squash the following into the final 
commit of the series:

and even with that fix, PCIe now doesn't work:

Perhaps there's some obvious mistake somewhere you can find by code 
inspection. Otherwise, let me know if you need me to debug that.
