boards/enclustra-sa2: add new board (HELP NEEDED)

[David Picard]

Hello,

I'm trying to port the Enclustra SA2 module. I started off the Terasic 
DE0 nano Soc board, that I could run with success previously. They both 
have a Cyclone V SoC FPGA. I added some pr_debug().

My code is here, in the board-enclustra-sa2 branch:
https://github.com/dpproto/barebox

It hangs when the execution jumps to the uncompressed Barebox image, and 
I'm really stuck.

Enclustra provides a U-Boot configuration, with handoff files. I tried 
to compare them with those I copied from a sample Quartus project they 
provide too. I couldn't notice striking differences, although it's not 
easy to compare because they used an older version of Quartus.

- The addresses and sizes in the log output below don't seem to exceed 
SDRAM boundaries, do they?
- Any hint on anything to check?

David
