Hi!
I am trying to switch to as much current vanilla SW as possible on Xilinx
ZCU102 evaluation board. But I am stuck at a very early stage.
I've got U-Boot + SPL + Linux kernel & userspace compilled, but even after
trying hard I had no success in running SPL to read ATF, not even speaking
about the main U-Boot.
I keep getting (debug info included):

### ERROR ### Please RESET the board ###
The base address is AFAIK correct and the SPL itself has been successfully
loaded from this very SD card. I suppose MMC2 lines to be a kind of
necessity.
I tried a few versions of U-Boot, including the last snapshot release (as
shown) with exactly the same results. Any ideas?
Thank you!
